Let me start by saying that a few weeks ago I totalled my little truck. I have always said that my next was going to be a 2500 diesel. I'm looking at 02-04 models. Well, I find an 02 in good shape, $19k with about 93k miles, leather & crew cab (what i've been looking for). But the only problem is that the whole frame is rusting . I don't know if this truck came from up north where road salt & other chemical stuff have started the frame to rust. Is this something that can be sandblasted and fixed or would the frame just rust through & the cab be left laying on the road in the next few yrs. If its something simple that can be fixed, how much should the seller wiggle off the price if any?
