New 2027 Forest River Xlr 366BX

The 2027 Forest River XLR Boost 366BX is a large fifth wheel toy hauler built for travelers who want serious cargo capability without giving up residential comfort. With a 43' 6" overall length, wide-body construction, a dedicated rear garage, multiple living zones, and impressive carrying capacity, the 366BX is designed for everything from motorcycles and side-by-sides to extended camping and off-grid adventures.

The rear garage provides a versatile space for hauling toys, storing outdoor gear, or converting into additional sleeping and entertaining space once you arrive at camp. Available features such as a ramp-door patio system, three-season rear door, Euro garage chairs, and rear power awning allow the garage area to become an extension of the living space.

Inside, the 366BX features a residential-inspired kitchen with a 10 cu. ft. 12V refrigerator, three-burner cooktop, 1.5 cu. ft. convection microwave, stainless-steel sink, residential-style kitchen faucet, and decorative glass cabinet doors. A 30-inch 5,000 BTU fireplace adds to the comfortable interior atmosphere.

The XLR Boost is built for year-round adventure with laminated 1.5-inch walls featuring high-density foam insulation and aluminum framing, fiberglass roof and floor insulation, an insulated enclosed underbelly, and a 35,000 BTU ducted furnace.

For extended stays and dry camping, the 366BX includes solar capability and offers generator and fuel-station equipment depending on configuration. The X-Package includes a 40-gallon fuel tank with pumping station and generator prep, while available equipment includes an inverter and a 6.0 NPS generator.
