My son just bought a '94 Ram 2500 5 speed with a 3. 54 rear, and I might occasionally need him to tow a yard tractor around for me. However, depending on what kind of tractor I decided to buy, we may end up exceeding the 14,500 lb GCWR for his truck. The trailer weight with the tractor will be between 8,000 - 13,000 lbs, which would put the GCW for his truck at between 14,500 and 19,500 lbs. I've heard plenty of stories about people going way beyond the towing capacity of their Rams and doing just fine (we hauled 20,000+ with our old F250 fairly regularly, which was rated for 18,000, and never had a problem), but before we start towing with my sons truck I wanted to check and see if anybody had any thoughts on what might be the limiting factor for towing capacity on a '94 Ram. I would think cooling and breaking would be the biggest things to be wary of. Will we be alright with the stock cooling system or would it be worth while to get a more heavy duty fan or something? Will we be ok in the hills w/o an exhaust break? Anything else we should be thinking about? Thanks
