Brandon, I just took delivery of my 36QBOK last month. Like you, when we decided on this model, I had a decision to make, as I had a very nice EFI Live tuned 08 2500HD and was looking for others towing with the same combination. I crunched all the numbers and was sure that I'd be over in pretty much every category, in spite of the power train being more than capable. I looked at doing the exact things Baron suggested-bags, sway bar, upgraded tires, and adding a leaf to get to where a 1 ton SRW truck's numbers would be, and still would have been over in more than one area. I decided to trade my 3/4 ton for the 1 ton dually in the end, mostly because I know that the worst time to realize that you need something is the moment you find yourself needing it and realizing you don't have it. At the end of the day, you're looking at putting a 42' sail behind you and all your beloved in the vehicle with you. If you decide to stay with the truck you have, definitely take steps to make it better suited. We all see setups that raise our brows for one reason or another, and hope/pray that nothing happens to make that person's choice affect us. Again, I never hooked up to the 36QBOK with the 2500HD, but having driven both trucks, I'd say I feel far more confident that I made the right choice after feeling the way the big 5er feels back there. By all means-it's a beast of a trailer. Congratulations and good luck, it's ultimately going to be you that decides, after you tow it.
