Thanks. I've got an AT4 coming sometime soon, and I've been having trouble deciding what rims and tires will work...I'm not crazy about having to trim anything...seems like anything beyond a zero offset requires trimming. I like the way your setup looks.

What size tires and rims?

Did you have to do any trimming to get those tires to fit?

I'm new to this forum, and not a current owner of a GMC but looking to buy one; could use some input. My current truck is a '12 F150 Platinum with the ecoboost and max trailering package. I'd like to buy a '20 GMC SLT with 6.2 NHT and the trailering mirrors(I absolutely won't buy anything without good trailering mirrors). Unfortunately GMC still won't sell me one...had one on order during the strike then GM said parts are back ordered and cancelled the order. Now they trailering mirrors aren't an option anymore on the SLT. So, I've started to look at the AT4, because I can get the trailering mirrors and I do like the looks/lift of it better than the SLT anyhow. My concern is towing my 30' TT, with a dry weight of 6800 lbs, tongue weight of 880 lbs. The payload on the AT4 I drove the other day is only 1540 pounds(300 less than my F150). So I will be maxed out on payload with just the camper and people, and getting close to max GVWR with all the other gear if I can pack it to keep the weight on the rv axles. With my F150 I've had no trouble loading a half bed of firewood plus all the other gear(thus probably overloading it as well), but I'm not confident that the AT4 would do as well. The AT4 I test drove the other day felt a little less stable than my F150(could be because of the lift/tires). Anyone have experience towing with the AT4, maybe with sumosprings/timbrens added on? Airbags are something I would like to avoid. I do use a wd hitch, and I only tow around Michigan so no hills to speak of, but my wife ends up towing the camper by herself quite often so I don't want to purchase a truck that she isn't going to feel comfortable in.
