| With any vehicle, if you do a lot of towing, a major concern should always be your transmission. I had a 28 foot travel trailer for a while and it had electronic brakes and I towed with a 3/4 Chevy. In addition to the tow package I ordered when I bought the truck new, I also had dealer put on an after market transmission cooler, along with the one included in the package. I now have a Yukon XL and an 18' boat and I never move the boat without making sure the tranny is in "tow mode". Cuts mileage dramatically but gas is cheap compared to a rebuilt transmission. | |
