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
~6,728 lbestimated as towed, for 2 people

dry weight 5,478 lb + fresh water (54 gal, full) 450 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 around7,480 lb (10% margin)
GVWR (the sticker maximum)6,926 lb
Tongue weight, loaded~941 lb (14%)
Cargo capacity1,448 lb
WHICH TOW VEHICLES IT FITS — 60 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 235S's published weights changed mid-run.

FINDING ONE

Common — usually several for sale within a day’s drive. Why: Forest River is a volume manufacturer; 8-year production run; still in production; an uncommon body style. Estimated from build volume and production span — not a count of live listings.

THE READ

Same 24'10" box as the 233S but trades a tent end for a hard-wall sofa slide.
