Queen Wall Bed
Swing-Out 32" TV
Full Bath
16' Awning

This versatile travel trailer is the perfect couple's unit! There is a front queen wall bed that can be put up each morning so you can dine at the fold down table/dinette. The full kitchen with a three-burner range and 12V refrigerator will let you make meals each day, and the residential sofa with built-in recliners are within a slide out for more space and comfort! And the sofa is in perfect view of the 32" swing-out TV! You can relax outdoors in the evenings under the 16' awning, then head inside to wash up in the full bath before bed!

Each Back Country MTN TRX travel trailer by Outdoors RV is designed for camping off-grid plus you can go off-road, camp in national forest or even enjoy primitive style camping! Built with a custom-built cambered off-road HD chassis, Mountain Extreme thermal pane windows, 16" Goodyear Endurance radial tires, plus more Climate Designed Four Seasons features allowing you to camp during any season. Some other standout features include a 24" Xtra tall power tongue jack, an HD full fiberglass front cap, and a Cummins Onan 3.6k on-board LP generator to keep your adventures going.
