Get access to the last 6 months of Local and National Auction Monthly Sales Reports from your busy friends, then compare those prices while you shop others, dealers, private, ect.. Sounds like you are open to a few different models and that will help. Get a current NADA book and try to pay around the loan value for a nice truck, if its loaded, and has lots of aftermarket upgrades, and with low milage in awesome shape, then the book is not much help. Good luck. I do have 3 guys that could help you out, they are in Forest Lake and Maplewood MN. They know their trucks well. If that is not to far P M me.
