Cat 350HP Diesel | Brand New Tires | New Radiator & Alternator | Solar Equipped

They say "Tiffin owners are owners for life," and one look at this Phaeton 40RH explains why. This is a premium "side-aisle" coach that combines the classic, heavy-duty build quality of the mid-2000s with a massive list of modern mechanical and tech upgrades.

The "Bulletproof" Mechanical Refresh While other 2006 coaches are showing their age, this one has been strategically revitalized. We?ve spent the money so you don?t have to:

Road Ready: Brand-new tires all around and upgraded shocks and stabilizers for a ride that is smoother than most modern rigs.
Cool & Charged: Brand-new radiator and brand-new alternator recently installed.
The Powerhouse: The Caterpillar C7 Turbo Diesel (350HP / 860 lb-ft torque) paired with the Allison 3000 6-speed transmission is a legendary combo known for million-mile potential.

Off-Grid & Luxury Living

Solar Power: 3 Solar Panels with a dedicated battery bank and a 2,000W inverter allow you to enjoy the quiet without constantly running the generator.
Modern Media: Upgraded with Smart TVs in both the living room and bedroom, plus an Auto-Seek Satellite system.
Residential Comforts: Residential fridge/freezer, convection microwave, Corian countertops, and a combo washer/dryer.
Clean & Pristine: No smoking, Cream leather captains' chairs (they swivel to join the party!), and a central vacuum system.

Exterior & Utilities

Self-Leveling: Upgraded with Big Foot Hydraulic Leveling?the gold standard for stability.
Power Everywhere: Large power retractable patio awning, power door awning, and two slides with toppers.
The Quiet Diesel: Onan 7.5kW generator provides enough juice to run both A/C units and the furnace simultaneously without breaking a sweat.
Storage: Full pass-thru basement storage on a Freightliner XC Raised Rail chassis.
2 new chassis batteries and 8 new house batteries as of 2/11/26
