Thanks for the links guys.
I took the truck in right away to the closest dealer while on my trip to Idaho last week. The dealer said no warrenty because I over loaded the truck, I paid out of pocket to get fluid changed to 75-140w and get my truck back. The truck has 2400 aprox miles on it.
I weighted the trailer empty today (3700lbs) the Viper weight is 3500lbs+ my lawn mower 450lbs. They said the truck is only rated to tow 8000lbs. is I'm building a case against them. (very small dealer in SE Colorado)
