2026 Sierra 2500DH AT4 bed height & 5th wheel towing

[johnm1]

I'm looking at a 2026 Sierra 2500DH AT4 and I've heard that the 2500HD AT4 has a 2" lift (from factory). Is this true or is the 2" lift only on the 1500's? Either way, how is the clearance from the bed rails to the bottom of the camper "over hang" on the AT4?

Pretty sure the lift is an actual level and only applies to the at4x

Bed rail height to camper is a function of the 5th wheel hitch set up. Sure with a lift it changes the rake of the camper and you can cause a slight pinch point with certain motions. Short 5th wheels are more susceptible, and longer not so much. There are guys towing 5th wheels with 4-6" lifts. I had a 2" lift and airbags on my 2019 short bed with a bed mounted cross tool box and a 32" 5th camper. No issues..

If really concerned install a lift in the camper, but generally not needed.

I understand all of that but, our current 5er sits nice and level when hitched to our 2013 GMC 2500HD and I'm looking for people who know if the 2026 AT4 sits higher than a 2026 non-AT4 ... which I should have explained more clearly in my original post. I know the 2026 AT4X has a lift but I don't know if the 2026 AT4 does ... or doesn't have a lift ... again, compared to a 2026 non-AT4.

Gotcha.. well if it does, the 2" shouldn't be an issue... Good luck

Welcome.

No lift on the HD AT4, LD AT4's have the 2" factory lift.

I pull a Montana on my AT4 with the B&w and it sits nice and level. Changed the bump stops to the timberin and no other changes were needed
