I do not see alot of talk on the L92 6.2. I am looking at getting an 07 Yukon Denali to pull an 18 - 20' enclosed trailer for my sons gokarts. Are the gear ratios listed on the first page good for the Yukons? I really dont want a 3/4 ton, will the the Yukon or the LTZ 6 liter Suburban handle this? I am more acclimated to the 2500 and 3500 trucks just getting tired of the high Diesel and maintence. Thanks for the help.
