The Platinum III is Coach House's Ford Transit gas coach, a roughly 25-and-a-half-foot B+ built on the Ford Transit 3500 (178-inch wheelbase) with the 3.5L EcoBoost V6 (306 hp, 400 lb-ft) and Ford's 10-speed SelectShift automatic, with all-wheel drive available for snow and light gravel. It is the friendlier-priced gas alternative to the Mercedes-diesel Platinum II, and it keeps Coach House's defining one-piece, patented seamless fiberglass shell — no rubber roof, far fewer seams to leak. The 250 floor plans pair a private, fully enclosed toilet and shower with a well-appointed galley (refrigerator-freezer, convection microwave, pantry) and a fully ducted A/C system, with five interior decor finishes. It carries an 11,000-pound GVWR and 31-gallon fresh and fuel tanks. As a low-volume model the Platinum III has thin individual review coverage, so the brand-level 4.9 RV Insider average is the better guide. The honest trade-offs: the EcoBoost V6 is less frugal than the Sprinter diesel on long highway hauls, it is still premium money for a gas B+, and Coach House's dealer network is thin. For buyers who want the seamless-shell build, available AWD traction, and a lower buy-in than the diesel coaches, the Platinum III is the lineup's value play.
