Yes and I have almost 1 hr commute everyday to work

Anyone swapped out these horrible Rancho shocks yet, I called Fox and they said it would be quite awhile. Anyone know of anything better? I hate the "boatiness" at highway speeds Thanks in advance!

Thanks for the spirited discussion, looks like consensus is, there isn’t one. i assure you that my Suburban receptacle is higher than the AT4, I had to remove the drop and install a straight one. On the 2500, I have only owned one and it was a drw and a Royal pain to drive in the city and to park. spoiled on pulling the trailer I have a Seneca that I normally pull it with but wanted something else to replace my Suburban as a daily but still be able to pull the trailer adequately without getting the RV out. Included a couple of half ass pics but you can see it’s on the bump stop and this is with an aluminum trailer without my car loaded.

Thanks for the replies! The empty ATC trailer (3642lbs) with the proper hitch receptacle height still has the suspension on the bump stop when the trailer is empty, my 2015 Suburban (1/2 ton w. 5.3) will not hit the bump stop unless the trailer is loaded and then only on bumps. After research I should have gotten a Max tow package but unfortunately not avail on AT4 or Denali, pretty sure the issue is from the cheap off road shocks and the springs. I incorrectly assumed the truck would have more towing capacity in the suspension than a half ton 5.3 Suburban My dealer has agreed to take the truck back in trade so it looks like my choices are: 1) Keep the AT4 and look at a load leveling hitch, air bags, shocks, springs or a combination of those 2) Get a Denali and hope the Denali's adaptive ride shocks will adjust enough with the trailer to keep it off the bump stops 3) Get a SLT with a max tow package (will lose the color matched bumpers and quite a few other features) and cost is the sam 4) Get a 2019 2500 which is more money, not as user friendly around town, harsher ride and more $$ I have to do something pretty quick to take advantage of the dealer's generous offer to take the truck back

Went from a drop hitch to straight, trailer was same height

You may have the "Max Tow" Package, after further study I see that the AT4 & Denali do not come with and it's not available on either model, forcing someone that wants to tow into a Sierra with a Max Tow option, hard to believe that is needed for such little weight

Believe it or not my 2015 stock Suburban hitch receptacle sits 2-3" taller than the "lifted" AT4

Thanks Dan for the reply, can you suggest a specific model/brand (direct fit) for this application I really appreciate it Best Regards, John P

Brand new 2019 AT4 with 6.2 and 10 speed, hooked up my 24' ATC aluminum trailer before I put my car in it and it bottoms out on the bump stops, just put my 2945 lb race car in and the truck, now sagging in the back so bad I had to change receptor and ball out just to release the jack on the trailer Drove it around the block and it steers like crap due to the suspension being bottomed out This truck supposedly has 9k plus towing capacity? My 2015 Suburban w. 5.3 is perfectly level when towing the exact same load Anyone with same towing problems?

What are you guys doing for the editing of the stock calibration for the taller size tires? The taller tire without reprogramming should make the truck short shift resulting in the RPM the truck shifts at being lower
