I had a 2004 2500HD crew cab shortbox and pulled a 36.5 Landmark 5er. It did much better after adding the Ride-rite air bag package which leveled it up. Handled much better. The LLY can pull it if you have fixed the LLY overheating problem. More on this on the Duramax forum if you look up LLY overheating issues. I added an AFE turbo inlet manifold, 3" Banks inlet tube and an Earl's trans oil cooler. Read the Allison owners manual on transmission operation. Its online somewhere if you didn't get one. I can understand keeping your truck if its paid for.
I added the S&B inlet, it is an LLY.. All else is stock, I suppose timbrens could be added. Hesitant to invest too heavily in it if it turns out to be struggling, at that point I'll pony up for a new 1 ton.
Never saw high trans temps hauling my 13k loaded gooseneck race trailer, is the trans cooler a weak point, too?
