Description
2008 Tiffin Phaeton 40 QSH Diesel Pusher Low Miles, Pre-DEF, Excellent Condition
Up for sale is my low-mileage 2008 Tiffin Phaeton 40 QSH. This generation sits in a sweet spot: more reliable pre-DEF diesels with modern styling that stayed current well into the 2010s. Its one of the best values youll find for a high-end, dependable diesel pusher without liquidating your retirement.
This coach is powered by the larger 8.3L Cummins 360 HP engine (upgrade over the base 6.7L in most pushers), which runs at lower stress and has proven extremely durable. Its built on the Freightliner Industrial chassis with full air suspension that rides like a luxury bus. Tiffins construction from this era is known for lasting: true solid wood cabinetry, real Corian countertops throughout, hydraulic slides/ leveling, and a one-piece molded fiberglass roof cap.
Key highlights:
Only 45,000 miles
Pre-DEF no diesel exhaust fluid system to maintain
8.3L Cummins 360 HP smooth, strong, and reliable
Allison 3000 MH Transmission - The dominant workhorse in Class 6-8 Commercial trucks
Runs ultra-smooth and fires right up every time
Tires at ~90% tread
7.5 kW diesel generator (surprisingly quiet), Recent oil change
All appliances working
King bed + pull-out couch
Power-actuated entry step
Awning in good condition
Massive underbelly storage
Propane extension for outdoor fire pit and grill
Roof caps and skylights recently resealed
Passed CA smog last month
We use it every couple of months for local Southern California weekend trips. This keeps all systems exercised and maintenance current. Im a mechanical engineer by trade and particular about diesel and powertrain care regular oil and fuel filter changes are standard. My wife and I have owned nearly every type of RV (travel trailers, toy haulers, Class C) and this diesel pusher is by far our favorite. The experience is in a different league from gas Class A or C coaches.
This is a well-maintained example of a highly regarded Tiffin that is ready for many more years of reliable travel. Only selling because I bought a diesel dually truck so I could have both a truck bed camper for boondocking and a 5th wheel for lux resort stays.
