Hi we have the younger brother of the 6.8 the 5.7. Having a smaller truck weight was the issue. We had a couple issues which I was able to take care of. The factory did't do their best to help with the issues. I could sense going into this that this was the way it would be. We like our setup for being built in 2011. The newer ones have changed. The insides have less storage as far as the 5.7's go. They seem to be well built but only time will tell. I do like the fact that there is no wood no rot. I think if in a perfect world I would get the biggest one and plan my own layout. Good luck with your search. Bill
