Engine Update

After two years of set backs, Covid, emergencies, parts issues and so on, Myrtle’s engine is nearing completion. We are taking her original 318 Poly to a 408 cubic inch stroked poly. We explored many options before this including Hellephant / Viper / Demon / Magnum crates, restoring a street Hemi and even just a simple rebuild of her current engine. 

Ultimately we decided to save her original, low mileage, strong engine that has served her well for over 50 years. The re-built motor will give more torque and horse power for those mountain roads and is totally bad ass. When the motor was stripped we discovered it was John Deere green! As you can see in the photos  her block has been painted red in line with 1964 poly engines and converted to a vintage 4 barrel Weiand intake manifold. The engine is still being finished - updates to come! 

Anyone can buy a new motorhome but I fell in love with this old girl Myrtle and I wanted to save her heart. We knew this would not be the cheapest and easiest route, but the best adventures are on the road less travelled. 💙

Engine overhaul!

Last year Myrtle went into Dale Adams Automotive Specialists for a major engine overhaul. The goal is to stroke and bore her original 318 poly engine to a 408. This article gives an idea of the plan: How To Give A 318 Poly Engine More Power – Mopar’s Rodney Dangerfield Part 2 ! Below are two before overhaul pictures. 

This kind of build takes a lot of time to collect and machine the necessary parts (and a good dose of cash). We have brand new forged aluminum pistons from Ross Pistons.

There has been a long wait for the cam core which has delayed the build, but the cam manufacturer finally got them delivered and will soon grind it with our desired poly lobe profile. It also took a while to find someone to rebuild the rockers so they will be suitable for the rest of our rebuild.. This means almost all parts are here and Myrtle is expected to be ready in May! Stay tuned for more updates!

New front wheel cylinders and brake shoes

The wheels are notoriously difficult to remove on the old travcos with the lower fibreglass skirts. It involves: Jacking up on frame and letting suspension sag, on passenger front wheel turn wheels left, repeat the other way on left and lots of wiggling. Also it was jacked up quite a bit but that still doesn’t help with the tight clearance front to back and side to side around the bolts. On ours the driver side is also reverse lugs. It’s a tough removal!

We replaced the front wheel cylinders and brake shoes. The parts were from Napa Canada; wheel cylinders 28720 and 28721 ($55.00 each), and brake shoes TS-33a Proformer ($52.00 a set). Our vintage manual is great help for mechanical work and copies can sometimes be found on Ebay. Some photos of the manual and work below.

New brake booster

Myrtle's brakes were a bit soft so we embarked on the adventure of replacing her brake booster. Myrtle has a single hydraulic system with one Midland Ross brake booster; #C-462. Refurbished boosters are sold by a few companies. Unfortunately the first one we ordered online was not a match for our booster, as you can see from the photo below, it is smaller than our original one. It is stamped Midland #C-8400-4, and we will be looking to sell this refurbished one as it can not be returned for a refund.

Upon further investigation with our Mopar Parts List manual, the mopar part number (1921313) quoted in the receipt for the smaller booster is actually for a WM300, listed in the book as "Conventional cab - Gasoline Engine 4x4 drive." Motorhomes are all listed as "M" only, and Myrtle is a M375. The Mopar Parts number for a brake booster for a M375 is 2230707. 

Below the photos show the front of the Mopar Parts List manual,  table of contents, Model Specification section, booster cylinder parts information, what a WM300 looks,  and finally and diagram of the brake system. The diagram has reference numbers which them match mopar part numbers in the parts section of the book.



Luckily we were able to connect with a local company in Calgary; Fleet Products/KBR Brakes, who were able to quickly identify the correct replacement and had one in stock! This company has an American counterpart as well; Power Brake Sales. This website was super helpful in trouble shooting and installation: In addition our vintage Dodge Trucks resource book was quite helpful, a few excerpts are below:

The new booster is a Midland Ross C-462, installed, all nicely refurbished and painted. We also found a new booster air cleaner 1/2 inch (part number 2503225).

Pump Problems

This season we needed to replace two pumps. The first was the fuel pump. There was some difficulty in getting it as the person working at the first place we tried was unable to look anything up with out a part number and insisted they were all electric, even though the mechanical fuel pumps are common on older trucks. Thankfully we found educated staff at the local Auto Value and got a Carter mechanical fuel pump replacement (part number M6866), which we installed ourselves. The pump was inexpensive, under $40.00.

The second pump was the water pump, which we discovered was broken, as we were heading out for our first camping trip of 2016. We apparently left it on for months with an empty tank, thus burning it out. The new one auto shut off. We found a SHURflo brand one (part number: 4008-171-E65) at an RV store on our way, planning to install it once we got set up at the campsite. A warning to others, confirm if your current water pump is wired for AC or DC. Our pump was DC and we bought an AC one. With some extra effort, we were able to make it work as we re-routed AC instead of DC. This pump was unfortunately far more expensive than the fuel pump, coming in at $330.00.

So now Myrtle again reliably pumps both fuel and water!

Mini Myrtle Model

I was lucky to receive this gift, a wonderful, extremely detailed Neo 1:43 resincast model of a 1963 Dodge Travco Motorhome! Description from the website: "The Dodge Travco was in production for nearly twenty years from its launch in the early 1960s and externally changed very little during that time. No date is given for the example modelled but looking at the grille arrangement and photos of the real thing we’d place it in the mid-60s. The rounded shape is very well replicated and through the neatly fitted windows we see plenty of interior detail with a sofa bed behind the driver’s seat, dining area behind the side door, full kitchen and to the rear a fixed bedroom."

So you want to buy a Travco...

2015 - Camping in Banff, Alberta

I adore Myrtle but she has her difficulties. I see many people very eager to get a Travco without considering the work involved. I understand this, I fell in love with a 1963 model and became obsessed with buying one. We had never owned an RV before and we had no idea about the costs, work, and time needed. None of this discouraged us from eventually purchasing Myrtle, for $5000.00, and driving her home to Alberta from Montana, in 2008. Her interior was very complete, she was in working condition, and made the 800+ KMS drive home. However, as we found out later she still needed a lot more in immediate repairs plus the regular ongoing maintenance. I don't want to discourage anyone else from buying one of these lovely old motorhomes, but I want to share some things to consider before making the commitment. To be successful with a Travco you need the following; time, money, patience, and either mechanical and renovation skills, or more money. And even with more money, it is advisable to have at least some mechanical skills to source parts and take care of more minor on the road issues. In addition, I recommend good RV roadside assistance coverage, we opted for RV coverage via AMA.

When you buy a vintage motorhome you are buying both an antique car and an old house. With a vintage trailer you can tow it with a newer vehicle and take your time working on the 'house'. With an old motorhome you do not have that luxury; both the living quarters and mechanical need to be working or you will soon find yourself stranded. While we've never owned a vintage motorhome before Myrtle, we did rebuild a vintage car (1970 Dodge Dart) and we do many of our own house renovations. We also have the support, labour, and extra tools, of my husband's very talented parents.

Time: The old Travcos take more time for everything. From sourcing parts, to slower speed on the highway, to repairs and getting ready for the camping season, you must budget the time needed. And sometimes they may break down on the road which means extra time getting there or getting home. If you have good mechanical and home renovation skills then you will save money but spend more time working on your unit.

Money: There will be costs for parts and repairs. For example we have invested over $1000.00 just in new wood and stainless steel screws. The windshields are also very expensive to replace, so really check out the glass before purchase. Replacing Myrtle's windshield, and re-sealing the rear window cost over $3200.00 (and a bit of work to find a shop willing to do it locally!) Once in Canada she also needed to pass a safety inspection to be registered, and completing the necessary repairs for just this aspect was $8,800.00, beyond the many repairs we had already done ourselves. This included work on all brakes, steering, driveline, suspension, tires ($2600.00 here alone!), speedometer etc. We also later needed a new muffler and exhaust at a cost $700.00 (parts only), new exhaust manifold which we thankfully found used for $20.00, but it took many hours of our own labour to install both. You will also need the required tools for any repairs you want to do yourself, and place to do the repairs. Most storage facilities do not allow you to do mechanical work onsite, but thankfully we store ours on a family acreage.

Mechanical and Renovation Skills: We spent 2.5 years of regular work on Myrtle to get her to point that we could safely and comfortably camp in her, and we had the help of my husband's very skilled parents. We continue to do repairs and refinements yearly. To start, I definitely recommend looking into an electronic ignition to replace the ballast resistors which always seem to break (or travel with extra ones!) Sometimes the repairs are minor, like replacing the battery. However, as with all things Travco, that is not always as easy at it seems. Last year Myrtle broke down at the gas station on the way to our first camping trip of the season. Her batteries are inconveniently located under the floor behind the drivers seat, and have to be lifted up and over the holder while underneath the vehicle. The batteries are very heavy and this is a difficult maneuver. After removal, my husband had to take a cab with the batteries to a local store and purchase new ones, while I waited at the gas station with Myrtle blocking the pump. Our lesson from this is to trickle charge the batteries at the end of the summer season and to take a dry run around the block well in advance of the first trip of the next season. We also always travel with an extra battery.

You also can't easily get a part number from the current installed parts, so it is helpful to have working knowledge of mechanics to determine what will work. Record everything you do find that works including; the part number, where you purchased it, receipts, and I suggest a photo as well, because you may need another one in the future!  For example windshield wiper motors and arms took quite a bit of hunting; the motors were found at a marine store and the arms found at Traction Heavy Duty Parts a division of NAPA. NAPA has actually been a terrific resource, especially the more experienced staff, who can help source needed items. If you do not have the mechanical skills and/or home renovation skills you will spend more time and may be challenged to find people willing to work on your Travco. We found a local garage, Dale Adams, that understands vintage vehicles and has a lift capable of lifting a Travco, for the aspects we can not repair/maintain ourselves, like suspension and wheels.

These costs and labour noted above do not take into account many other mechanical items and most of the interior which included the following and more; re-wired the entire unit, new plumbing including water tank, new subfloor, new floor tiles, new kitchen cabinets, rebuilt closet, new front seats (from a wrecked modern motorhome, which were then reupholstered), new seat belts, new benches, new mattress,  replacing portions of the water damaged wood panelling, new ceiling, new insulation, new welded panels under driver/passenger seats, sanding the entire original wood and new wood walls and varnish, pulling and re-sealing every window (look into butyl tape!), 2 new roof vents, re-building 2 exterior access panels, reinstalling the exterior roof strip (which is a major source of water leakage and is something we recommend addressing ASAP), chroming the bumpers and badges etc. Myrtle's lovely original, gelcoat fibreglass also takes labour each year to get it looking in tip top shape (washing, cutting compound, polishing compound, wax). I am personally very wary of repainting these units, in addition to the cost, I am concerned about the long term durability of paint vs original gelcoat.  You get the point; you need to have carpentry, flooring, electrical, mechanical, painting and related skills, or the budget to pay someone to do the work.

Other general tips;  Consider the repairs, maintenance, completeness and condition of a unit before buying. Check out the rims, some units have split rims, which some people like to avoid, as it can be harder to find shops to work on them. (Myrtle had non-split rims but no spare rim, which was another adventure to locate, and took us to meet a lovely fellow Travconian in NYC!) Do not balk at an asking price until you understand the underlying costs and time. The bargain Travco maybe no bargain if you end up spending more time and money repairing it.

Another tip, find reference materials (shop manuals) for your specific engine and chassis; I suggest eBay or one of the automotive literature re-print companies.  In the older models it will not likely be called a motorhome reference guide, but I have seen a few 1970's Dodge Motorhome chassis guides on eBay. The following book we have found to be invaluable in our restoration:

After all this, we love Myrtle. We love her comfort, vintage style, and thoughtful layout. We love taking her camping, to car shows and all the curious admirers. As far as vintage motorhomes go, we think the Travco is one of the best options with a steel frame, study chassis and fibreglass shell. Many other old motorhomes have a wood frame covered by siding. However, she still requires patience and care to ensure it is an enjoyable time. (To be fair, modern motorhomes require maintenance too). We view Myrtle as a hobby which makes the maintenance a bit more enjoyable. If you are still interested in this adventurous journey, check out the following resources to help you along the way:  Dodge Travco Motorhome Lovers Facebook page,, and if you have a 318 poly engine the Yahoo Poly Group and Polyspherical AKA Poly 318 Facebook group. If you are searching for a unit, craigslist is often a good place to start and compare prices and condition.

We wish you safe, comfortable and happy travels!
