WHAT ONE COSTS
$37,400est. used (2016, 10 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK
~14,244 lbestimated as towed, for 2 people

dry weight 12,860 lb + fresh water (70 gal, full) 584 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

GVWR (the sticker maximum)15,500 lb
Tongue weight, loaded~2,791 lb (20%)
Cargo capacity2,640 lb
WHICH TOW VEHICLES IT FITS: 19 OF 95

Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 370RL's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

WallsAzdel composite

RoofWalk-on
UnderbellyEnclosed

Coachmen (Mixed tier): Azdel composite sidewall panels inside and out, an aluminum cage, USA-made Dexter axles and 6-point auto-levelling are genuinely good bones for the money - but Coachmen towable QC is uneven and the line has been reshuffled twice (original 2008-2018 run, all-new 2019 relaunch, all-new again for 2026), so cross-generation parts support is patchy.

YEAR BY YEAR: WHAT CHANGED

  • 2016Final model year
FINDING ONE

Findable: a few listed nationwide most weeks. Why: Coachmen is a volume manufacturer; only 2 model years; 10 years out of production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Five-slide rear living on the 15,500 lb chassis - only two model years before the 2016 range reshuffle.
