Suggestion? You live in Michigan! Before buying any used truck to tow a 5er with, check the frame UNDER the truck to make sure it's not eaten out with rust from winter road salt over the years. I traded my first (gas) duly 3500 because the frame was rusting out and I had serious questions if the frame would tow safely any more. It was completely eaten away because of Indiana road salt winters. Body and cab interior looked great! But underneath it was in bad shape. Too bad, it had a fantastic engine and transmission too.
(just something to think about).
