I'd like to tow a 6,880 pound travel trailer (loaded with everything its about 7,400 not including other people in the truck) and the max towing for the truck says 7500lbs which seems kind of low for a 2500. Will my truck be ok? side note for the trucks made before 95 the max towing was 8,500lbs , does any one know why the change? my truck is a 1997, 5.7 with 4.10 gears. 106,000 miles.
