We can be 75' here in SD and boats, jetskis, cargo trailers, and utility trailers behind 5ers is pretty much the norm. If you aren't pulling a trailer with your 5er than there is probably a bike rack back there. Our neighbor has a double hitch on his rig that he mounts a bike rack and hooks up the boat. Even TT's pull smaller boats.
