Looking for an opinion. Picked up a new 2022 AT4 before Christmas, originally wanted a Yukon Denali Ultimate but they are still scarce. This one has lots of features but I didn't notice it was without a trailer package. I have an open car hauler and plan to haul a 1973 Corvette or a 1965 IH gasser when its done. Any thoughts on the AT4 reliability pulling the trailer if I dont have the trailer package? I do have the trailer brake gain package ready to be installed.
