04 Notes on this floorplan
What Prime Time does not publish for the Sanibel 3102 RSWB
Prime Time prints no GVWR, tire size, interior height, sleeping capacity for this model, so none is given. Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.

11 NHTSA safety record
NHTSA holds 10 recall campaigns and 1 owner complaint (model years 2005 on) against the Sanibel line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 1 complaint has been filed on this line — not enough to say what fails most often. It covers tires.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Sanibel line page.
