WHAT ONE COSTS
$51,500est. used (2017, 9 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK
~16,619 lbestimated as towed, for 2 people
dry weight 14,985 lb + fresh water (100 gal, full) 834 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.
You want a tow rating around18,470 lb (10% margin)
GVWR (the sticker maximum)18,000 lb
Tongue weight, loaded~3,549 lb (21%)
WHICH TOW VEHICLES IT FITS: 15 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 355's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

Heartland (Mixed tier): Heartland (Thor): heavily equipped laminated toy hauler with MORryde CRE3000 suspension, 7,000 lb Dexter axles and a walk-on roof, but Heartland's fit-and-finish and warranty service are inconsistent enough to keep it out of the top tier.
