I have toughted the 2500 and RAM and expressed opinions on almost every tow vehicle, but it comes down to the MATH. I like my rig but your fiver should not have to accommodate your tow vehicle. Your Tow vehicle should accommodate your fiver.
The problem is that people don't want duallies and there are no tires beyond 3200 pound max load. The only way around it is to buy custom wheels and use medium duty tires on a 350/3500 are whatever nomenclature applies to a 1 ton in the brand you are thinking about.
I let a car salesman choose my truck in the heat of the moment. Truck lots are not a good environment for me, and many will know what Im talking about. Between him and my wife who thinks that a Ram 3500 was a bigger truck than the 2500, I acquiesced. Always do the math then find the truck and go buy it. If they don't have it then order it.
I know most know most already know what Im saying here, I'm posting this for the guys that are thinking about purchasing a rig and have never owned one before. Do the math and the solutions will put you in the right truck.
