Hum, Got the 3:43 rear not the 3:2?? something like trailer package states. Got crap load of cameras. Got locking rear. Got the extra tpms from factory. Just don’t get it. Look like I have some of the trailer options needed but not all? Why even bother.

Have a 2019 AT4? With a 6.2. Has GM performance exhaust and came with TPMS for trailer tires. I purchased with 1200 miles on it and got good deal but now I’m wondering if I have the Max trailering package. Dealer gave me the build sheet and said I have Max package but I don’t see anything on build sheet. What should I be looking for? Truck pulls my 5000 pound travel trailer with no issues and trans temp never gets over 160 even with 95 degree temps outside. My older suburban used to run trans temps of 190-210 in same conditions and that has an oversized trans cooler so I was thinking the AT4 must have a large cooler from the factory. Anyway is there a code I should be looking for on the build sheet? Looking to get heavier camper and want to be safe.
