As my profile states, I had a Travel-lite TC on my 2011 Silverado 1500 LS.
I looked up the RPOs or as built codes of my truck. And found it was a "work truck" with increased strength frame, 3.73 rear end 5.3 gaser. I added AirLift air bags, E rated tires and Bilstiens shocks. All which were NEEDED. I also added an air dam between the cab and cab over to reduce buffering.
So check your truck! Others will say it will be ok, but you are stressing it to the max, and may be unhappy down the road.
We moved to a TT because of the DW. Wife is now happy now, life is good.
