Need more help with tow vehicle/truck trade/purchase!?

Start searching ebay for trucks. 4 year old truck with 140K miles is simply not worth getting for a long term tow vehicle. Remember, no matter what 1500 series you look at, in a crew cab I assume your going to have four adults or nearly adults. That alone takes up a lot of caego capacity. At the end of the day a 1500 crew cab could be nearly at capacity with just passangers and stuff.
