I love the truck. Lots of power to pull a good size trailer in the half ton class. I have also used it with a 8' slide-in camper that is over weight. It handles it well but needs overloads and a stonger frame to reduce flex. Performance problem is surging under decleration at around 3000 rpm loaded or unloaded, Cruise or manual. Overall mpg is 13 with a max of 17. Would like better of course. Sometimes the seat & mirror memory system act peculiar but shut down and start over and it comes up OK. When I lost my lug nut key, the dealerships (3) wouldn't remove or let me remove the locks from my other wheels without a charge even tho I paid for and ordered a replacement key. Bad policy.
