03 Reading Forest River’s figures
A maker’s published weight is for a base trailer; options and dealer-installed equipment add weight to any particular unit. The federal weight label inside the trailer carries its own unloaded weight, cargo carrying capacity and GVWR (49 CFR 567 and 571.120): read it on the unit itself before any towing decision.
