One has to wonder why so many equate, being overweight with their toad, automatically translates into danger for themselves, passengers and to others on the road, when in most cases, it just puts a strain on the rig's transmission in mountain terrain. Example.... and with our exact same coach on a Ford Chassis, the GCWR increases dramatically and because of the transmission, with all other factors being the same. Just wondering what piece of their engineering research, prompted these opinions? Now, are these specs. always a truism, or just one company wanting to advertise better and then worry about a few extra warranty claims later? As for hitch strength being the only factor, that should be the least of concern with a good structural inspection.
