I have some questions regarding towing, the owners Manuel of my 86(truck in sig). Says max gcwr is 1200 for a 6.9 Manuel transmission 3.55 or 4.10 gears. Well my truck weighs 6500 wet so that means I can tow 5500 no matter what. That seams like crap to me. With a proportional controller, air bags in the rear and a gooseneck hitch I can barely legally tow some trailers that are available to me empty. I am about to do a cummins and 5 speed swap and the truck should then be able to handel 12k on a trailer no problem. So is it really a big deal to overload if I'm not commercial? I feel like a extended cab or 4 door dually is your typical hauling truck and an 86 f350 one of those aparently can only haul what,3000 lbs? Also if I get pulled over how do they know my gcwr since only gvwr is on the sticker.
