04 Notes on this floorplan
What DRV does not publish for the Mobile Suites 41 FKRB
DRV prints no cargo carrying capacity, GVWR, hitch weight, 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.
05 How it compares
18,380 lb dry and Not published by DRV GVWR, against this model’s 19,440 lb and Not published by DRV.
