Built for long-range, off-grid travel, this 2010 Freightliner P2XL Sport-based expedition truck pairs commercial-grade durability with a fully integrated luxury camper. Offered by a private seller in Mansfield, Texas, this rear-wheel-drive platform shows 52,000 miles and is powered by a Cummins 8.3L diesel mated to an Allison 6-speed automatic transmission. Professionally built by Phoenix Custom Campers, this rig blends heavy-duty mechanicals, advanced suspension, and a highly optioned living space designed for extended remote use.
- Commercial-Grade Diesel Platform: At its core is a Cummins 8.3L diesel engine paired with an Allison automatic transmission—an established combination known for longevity and torque. The Freightliner P2XL Sport chassis is equipped with a fully adjustable air ride suspension system at all four corners, enhanced by custom-valved King shocks. Air ride seats and cab suspension further improve ride quality over long distances.
- Purpose-Built Expedition Construction: The camper structure is built from composite fiberglass panels with carbon fiber corner reinforcements and an all-aluminum frame. Insulation is handled by 3-inch triple-core foam, and double-pane windows help regulate interior temperature. A walkable roof deck with integrated rain catch system adds utility in remote environments.
- Expanded Living Space with Dual Slides & Loft: The camper features two slide-outs and a hard-sided pop-up loft, creating a multi-zone interior layout. The loft includes a queen-size mattress, while the main living area is anchored by a Flexsteel ultra-leather couch and a fully integrated entertainment system.
- Fully Equipped Interior Systems: Inside, the cabin is outfitted with powder-coated aluminum cabinetry, dual refrigerators, an exterior slide-out ice chest, microwave convection oven, and a two-burner stove. Additional amenities include a filtered water system, propane furnace, instant-on hot water heater, full bathroom with shower and macerator toilet, and LED lighting throughout.
- Entertainment & Connectivity: A 40-inch Samsung LED TV with surround sound is mounted on an electric lift, paired with a Focal audio system. A Winegard Traveler satellite system provides DirectTV access, while multiple cameras, GPS, and TPMS enhance visibility and monitoring on the road.
- Off-Grid Capability: This build is designed for автономous travel, featuring dual solar controllers, a flexible solar roof array, lithium 120Ah batteries, and a propane-powered Onan 2400W generator. The system is supported by 85 gallons of fresh water, 30 gallons of propane, and a 100-gallon diesel tank.
- Exterior Utility & Equipment: The truck rides on super single tires (replaced in 2022) and is equipped with an 18,000-lb electric winch integrated into a custom front bumper. Additional features include rigid LED flood lighting, Carefree electric awnings with integrated lighting, electric steps, and exterior storage boxes added post-build.
Freightliner’s medium-duty chassis platforms are widely used in commercial and specialty applications due to their durability, serviceability, and load capacity. When paired with a custom camper build like this Phoenix Custom Campers unit, the result is a true expedition vehicle—capable of extended off-grid travel while maintaining the reliability of a commercial truck foundation. These builds are often commissioned for long-term overland use, remote work, or full-time travel, where both comfort and capability are essential.
