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
~7,752 lbestimated as towed, for 2 people

dry weight 6,660 lb + fresh water (35 gal, full) 292 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 around8,615 lb (10% margin)
GVWR (the sticker maximum)8,480 lb
Tongue weight, loaded~1,059 lb (14%)
Cargo capacity1,820 lb
WHICH TOW VEHICLES IT FITS — 44 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 288ISL's published weights held steady.

Common — usually several for sale within a day’s drive. Why: Gulf Stream is a volume manufacturer; 12-year production run; still in production. Estimated from build volume and production span — not a count of live listings.
