HOW IT'S BUILT: 5/5
WallsAzdel composite
FrameAluminum
RoofWalk-on
UnderbellyEnclosed

Coachmen (Mixed tier): Alumicage aluminum framing with Azdel composite panels on both wall faces, a 5 in crowned walkable roof and a heated enclosed underbelly are above-average for a budget toy hauler, and every plan carries a 98 gal fresh tank and 3,400-4,900 lb of cargo capacity - but it is a Coachmen volume build with the usual ramp-door seal and slide complaints. Note the line is still in production in 2026, not discontinued in 2021.
