Wow, I am impressed, the Max cargo on my 2011 E-boost F-150 4x4 is 1411 lbs.
I tow a 25 ft. Dutchmen with slide, 5004 lbs. dry weight, 6400 lbs. across the scales when loaded for the road. That puts 750 lbs. on the tongue. With two adults, a large dog, and some camping gear it puts me near my max cargo limit.
Yes there are others that exceed their truck capacity but all you are doing is increasing the wear and tear. If you tow a few hundred miles a year it does not make much difference. If you tow several thousand miles a year it will.
Good Luck
