WHAT ONE COSTS
—price not published

The maker never published an MSRP for this floorplan. Unknown is not cheap — treat any asking price against comparable models, not against zero.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~13,460 lbestimated as towed, for 2 people

dry weight 12,660 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 around14,960 lb (10% margin)
GVWR (the sticker maximum)15,500 lb
Tongue weight, loaded~2,759 lb (20%)
Cargo capacity2,840 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 3450RL's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
