04 Notes on this floorplan
What Forest River does not publish for the Sanibel 40TRIPBR
Forest River prints no GVWR, tire size, interior height and 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
The weight label every RV trailer carries by law (49 CFR 571.110 and 571.120) governs the towing decision, not this page.

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.
