Since no 5 er toyhauler, I need to be able to get my 30 ft travel trailer out of my pole barn easier. 8 inches to spare is not much. It is a 94 coachmen 298fk and the tongue is heavy. I know the hitches are rated 500lbs and was wondering if with some bump stops temp installed, it would be too heavy for my front axle and steering? I have to go 60 feet back on flat ground with no turns. Thanks fellas, Tim
