04 Notes on this floorplan
What Venture RV does not publish for the Sonic SN220VRB
Venture RV prints no cargo carrying capacity, GVWR, tongue weight, tire size, interior height, grey-tank, black-tank 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.

5,320 lb dry and Not published by Venture RV GVWR, against this model’s 4,940 lb and Not published by Venture RV.
06 Loading it for a trip
