Why buyers love Marathon Coach
Marathon Coach has been converting commercial Prevost bus shells into ultra-luxury motorcoaches in Coburg, Oregon since 1983, and it is the largest and most experienced bus converter in the world. These are not factory RVs. Marathon starts with a bare Prevost H3-45 or X3-45 chassis — the same Volvo-powered platform that hauls tour buses for a million-plus miles — and hand-builds a custom residence inside it, identifying every build by a sequential coach number. The result is a true one-off: Crestron-controlled lighting and climate, Valid slide-outs that disappear into the bodywork, residential appliances, and finishes chosen coach by coach. Marathon sells both new builds and a large, daily-updated inventory of pre-owned coaches, and it backs them with three sales-and-service locations in Oregon, Texas, and Florida. The honest truth: new coaches start around $3 million and the conversion alone runs over $1.7 million, so this is the rarefied top of the Class A world. Below is the real lineup — the platforms Marathon builds on and what to know about each — with honest notes on what owners praise and what to watch, so you can shop a Marathon for sale knowing exactly what you are paying for.
Here's the part the lot won't tell you: the best Marathon deals are usually two to four years old. Let the first owner eat the steep early depreciation, then buy a coach that's already been shaken down, with the bugs sorted and the records to prove it. That's exactly the kind of unit our RV buyer's agents hunt for, and we run an independent inspection on every one before you wire a dollar. Already own one and ready to move on? We'll list and sell it through our RV broker service for the retail number it's worth — not the wholesale gutting a dealer offers on trade.
What owners love
- Reference-grade engineering on a commercial chassis. The Prevost shell and Volvo D13 drivetrain are built for a million-plus miles, and Marathon's conversion work is widely regarded as the best in the business.
- Genuinely bespoke. Every Marathon is a numbered, one-off build configured to the owner's taste — Crestron automation, Valid flush slide-outs, and residential appliances you will not find in a production RV.
- Strong resale and a real support network. Coaches from a reputable converter like Marathon hold value well, and the company runs full sales-and-service centers in Oregon, Texas, and Florida.
What to watch
- The price of entry is enormous. New coaches start around $3 million and the conversion alone tops $1.7 million; even pre-owned, you are in luxury-yacht financial territory.
- Operating costs match the price tag. A 45-foot, 55,000-pound diesel coach needs commercial-grade service, burns fuel at roughly 6–7 mpg, and demands a capable Prevost-experienced technician.
- These are big, complex machines. At 45 feet with four slides and dense automation, a Marathon is not a starter RV — inspect any pre-owned coach's chassis, slides, and electronics hard before you buy.
What Marathon Coach owners are saying
Marathon Coach is a low-volume, ultra-luxury custom builder, so it does not carry the kind of large owner-review sample you see on mass-market RV brands — there is no dedicated Marathon star score with hundreds of reviews. What exists is consistently positive and concentrated on the Prevost platform Marathon builds on: on RV Insider, owners of Prevost-converter coaches (Marathon among them) praise the quiet ride, the commercial-grade Volvo/Detroit drivetrains rated for a million-plus miles, and the long-term build quality, with the running theme that 'once you have a Prevost, you can't go back.' Industry reviewers echo it — a hands-on RV.com review of the Marathon H3-45 called it 'a motor coach that provides exceptional comfort and convenience.' Marathon also states it inspects, services, and warrants select pre-owned coaches with a limited six-month warranty before sale. Because the individual-model review counts are thin by design, we keep ratings at the platform level and say so honestly rather than inventing a score.
“The only bus I have ever had or driven that makes absolutely no noise.”
“Engine, transmission, will easily last over one million miles.”
“Once you have a Prevost, you just can't go back.”
“A motor coach that provides exceptional comfort and convenience.”
