Currently have a 3/4 Chev short box with a 7ft deck. Looking at picking up a small camper to start bringing along. I'll be hauling 2 quads on the deck most times so the deck will be extended open. Would it be too tight with the deck open with a trailer? Also would an equalizer hitch help pull some weight off the rear axle to help keep me closer to legal? Trailer I'm looking at only has about 500lb to tongue weight
