I am looking for a used truck and at first I was sure I was going to get a chev/gmc 1500 but with all the install work I am doing I am thinking a 2500 will be of better use. Issue: 1. Most 2500 are either work trucks that have been used to plow 2. Set up for heavy towing, 5 wheels and such. I will never buy a used plow truck... I am wondering if there are any issues I should look for in used trucks that have been used to tow alot? Should I expect early tranny issues? suspension issues?
