This past wkend attended OAKS, PA RV show. I saw on several travel trailers a rear folding "cooler" basket. It mounted to bumper (not into 2" receiver) and had a bracket on bottom to mount spare tire....
Does your TT manufacturer limit the weight on the bumper? Winnebago does, as do most others. Have you calculated the effect that adding weight to the very rear of the TT will have on tongue weight?
