RV Description

2006 Gulfstream Endura Max 6331 Pre-DEF Super C Powerhouse

Experience the power and reliability of a true Super C. This 2006 Gulfstream Endura Max 6331 is built on the legendary Chevy Kodiak C5500 chassis and powered by the sought-after 6.6L LLY Duramax Diesel engine. Because this engine predates modern emissions requirements, you get all the towing strength you needwithout the hassle of Diesel Exhaust Fluid (DEF).

Whether you are looking for a capable hauler for your toys or a comfortable, spacious home on the road, this rig is ready for your next adventure.

The Details

  • Engine: 6.6L V8 Duramax Diesel (310 HP / 605 lb-ft Torque)

  • Transmission: Allison 1000 5-Speed Automatic

  • Mileage: 77,000 miles

  • Length: 34 ft. 1 in.

  • Capacity: Sleeps up to 8 people

  • Condition: Well-maintained and upgraded

Upgrades & Enhanced Features

We have carefully curated this motorhome with high-end upgrades to make off-grid camping and towing seamless:

  • Towing Ready: Equipped with a Roadmaster Nighthawk All-Terrain Non-Binding 8K Tow Bar with LED lights.  (Inquire about the 2019 Ford Flex Limited included in a potential package deal).

  • Power Management: 2000W Inverter and a Victron BMS 712 Battery Monitor to keep you in control of your power usage.

  • Convenience: Battery watering system, electric entry steps, and an added low-pressure propane port for easy outdoor cooking.

  • Entertainment & Comfort: Dish Network Satellite system with (2) Joey receivers, and a premium Sleep Number King Size Inflatable Bed.

  • Eliminated the front cab window: We recently had a leak in the front window seal. As part of that repair, I chose to eliminate the front window as a possible future leak point. In addition, this window always caused considerable heat gain to the cab and drivers cabin. This fix eliminated those problems.

  • Electrical: 50 Amp power supply

  • Climate Control: 2 A/C units and a powerful 35,000 BTU furnace
