We had an 01 Yukon with the 5.3, not the XL. Tow package was in it too. We pulled a 27ft. Dutchman that weighed in at 7700# of which 1000# was tongue weight. It was a bit heavy for the shorter wheelbased Yukon and we were probably a bit over GVWR. Depending on the tonguw weight you want to pull, you should just start looking at trailers and find one you really like thats within the specs of the tow vehicles. You have to keep stopping in mind along with the safety of the family.
