Hey guys and gals! Newbie here and I have a question. I have an 04 Explorer EB w/4.0 V6 with 3.55 gears. I am changing the Hitch to a weight dist. class III as I have a 24 ft TT to tow. I am also installing an electric brake system as well. The TT will weigh close to 5000lbs when loaded. I have checked all the numbers on the door of the explorer and understand them but if I'm not going to pull up any long big hills and keep my towing local would this be allright to do? As well is it a legality issue also? Please help.
