The 2004 Tiffin Phaeton 35RH is a well-regarded Class A diesel pusher motorhome that combines compact maneuverability with Tiffin's signature luxury and build quality. Measuring approximately 35 feet 10 inches in length, this rear-engine model rides on a sturdy Freightliner chassis and is typically powered by a reliable Cummins ISB 300 HP diesel engine (with some units featuring the optional Caterpillar 3126 330 HP variant), paired with a smooth Allison automatic transmission for confident highway performance, air ride suspension, and strong towing capability around 10,000 lbs.
