You can tow at 65 but you'll have to do it in a lower gear and at higher RPM. I had an 09 GMC 2500 HD with a 6.0l gas engine. We couldn't tow in overdrive (6th gear) had to leave the transmission in manual and tow in 5th gear in order to get the revs up into the proper power band for towing the 5ver. Oh....and one other thing, you absolutely cannot tow with the cruise control on. Ours down shifted every 10 miles between Wichita and Holbrook, AZ. That's why I went to diesel.
