I have a new tow vehicle its a 2006 Yukon Denali XL. This weekend will be my first time hauling with it. My trailer is about six and a half thousand pounds loaded. The truck is a 6 liter and all ...
Congratulations on the new to you TV. Related to the "I do not know what gearing it has and if I should run in 3rd gear or if I can leave it in drive with tow haul mode on." My experience is with my Ford F150. I let the computer pick the gear. I put it in tow haul and enjoy the ride. Enjoy.
