I would stay away from a diesel, just because of your $10,000 price. You can find a 10k diesel, but you had better know what your are looking at. Being a Dodge lover I'd like to recomend one, but the advice of looking for a 6.0 gas chevy 3/4 ton is pretty good advice, they are common. Also so of the earlier Ford Super Duty with what I think is a 5.4 gas. To be honest, I've driven one and they don't have enough power to get out of their own way, but they are often priced to sell and no more often then you would tow, would probably get the job done at a great price.
