I am a first time buyer of a GM vehicle. Just purchased a beautiful 2010 like new Yukon SLE with 20" Denali wheels. (looks like a Denali)
I have a 6 speed with 3.08 rear and a 5.3L engine. With the 20" wheels I know this is not the best combo BUT...this is what I have. I will be towing a 4600 lbs TT (it has a WD hitch) about 3 times a year in mostly flat location. I am in Socal. It came with a PS cooler and I have installed a Trans Cooler and Brake controller. What else do you recommend? An engine oil cooler? 3.42, 3.73 gearing? Most of the time it will be a grocery getter on weekends only.
When I towed in the past , I normally cruise around 60mph on flats and take my time on hills...not in a rush.
Thanks for your time,
first time GM owner
