Oh, purchase the heaviest suspension truck you can afford. An SUV/half ton truck isn't equipped for extended towing. The problem is accelerated wear on the entire vehicle - really nails you on resel value as a mechanic can/should spot the signs of use. Also, use a good quality seat cover. I shampoo the seats once a month and the seat covers are removed and washed once every two weeks. This process greatly helps on odor control in the trucks. Make sure you have an oversized trans cooler if running an auto, although I prefer a manual. Overall easier on the vehicle when towing.
