I have a 04 hemi ram with towing package(has trans cooler, i checked), 3.55 gears. Need to tow a 24ft enclosed trailer that is roughly 7k lbs from NH to FL (about 1200 miles). Will it do it? Or will i burn it up? The truck has 204k miles on it now. Looks like a 7600 lb tow capacity, which means Im going to be pushing it in that regards.
