I have a 2009 Avalanche LS 5.3 L Flex Fuel truck with 3.42 gears. I have the towing package just not the HD cooling package. The manual lists a max trailer weight of 5,500 lbs.
My question is if the only difference between towing 5,500 lbs and 8,100 lbs is the cooling unit am I legal (and safe) to tow more than 5,500 lbs if I have installed a transmission cooler or is there more of a difference in truck set up than I am realizing?
In addition to the transmission cooler I have also installed trailer brake control and Timbren suspension enhancers and a weight distribution hitch.
I am towing a 3 horse aluminum trailer (2,700 lbs), 2 horses (2,600 lbs), gear (400 lbs) and 4 people (600 lbs) for a total of 6,300 lbs.
The Avalanche seems to tow fine achieving 8-10 mpg depending on the wind direction but my trips to date have all been approx 1.5 hrs or less from home.
Appreciate any opinions on this. The last thing I want is to be uninsured or to fry my truck.
Thanks!
