Epic Project! 1950 Marmon-Herrington Motorhome
Let’s see…. you have a vintage Marmon-Herrington bus lying around – hmm, what to do with it? How about converting it to a motorhome! Here on eBay is a 1950 Marmon-Herrington made into a 28-foot RV, complete with a respectably spacious wet bath, hallway sink, kitchen, a good-sized bedroom, and plenty of storage. The seller is asking $10,000 but he’s closing his business, so offers are welcome. The lucky new owner will be hauling this impressive coach home from Gray Court, South Carolina. Thanks to Driven by Faith Restorations for the tip!
If ever I wished a vehicle could tell its story, I would want this one to have a voice. We don’t know who converted it, or how it was used. We do know it’s mounted on a bus or truck chassis – the seller believes it’s a Mack – and it’s powered by a well-running 6-71 Detroit diesel engine paired with a Clark five-speed manual. The 6-71 is a six-cylinder, good for about 170 hp; the Clark gearbox is as stout as they come. But the condition of the rest of the systems is unknown; a restorer should expect to rebuild virtually everything.
The driver’s “office” contains a couch where the original accordion entry door would have been. That dash layout is interesting, with a few gauges mounted on a horizontal surface. The steering wheel is a throwback to the early days of buses – which was one of Marmon-Herrington’s specialties. The company made heavy duty truck components, particularly 4WD conversions. It eventually began manufacturing military vehicles, snowplows, trolley buses, delivery vans, and diesel-powered buses under its own nameplate. The Chicago Transit Authority purchased 349 Marmon-Herrington trolley buses in 1950, a significant hunk of the entire production.
Here’s that bathroom, currently used for storage but in surprisingly decent condition. For those not familiar with RVs, “wet bath” means you take your shower in the same room with the toilet; a dry bath supplies the user with a separate shower space. The stove sits in the aisle, amidst plenty of storage. A refrigerator is pictured but I’m not sure where it is relative to the stove. The rear bedroom consists of a mattress situated on a wooden platform, with storage underneath. Abundant windows help defeat the claustrophobia that can be a part of RV life.
This view shows the metal panels covering what would have been windows down the sides and the center entry door. I like patina as well as the next enthusiast, but I’d love to see this motorhome restored to as-new condition. Of course, we’re probably talking an “investment” of around $250k, right? What do you think it would take to resurrect this majestic motorhome?
