So the current truck I have has basically no rust on the cab, the doors have some surface rust spots smaller than a dime, the cab does leak through a light I believe, I've been going to change them. I put a reman steering box on two years ago, all new rear drums, reman injectors, new clutch flywheel rear main seal and a used take out transmission last year. So the rest of the truck is pretty sound, other than miscellaneous things that go bad like wires that break and I have to run new ones, the hood needs some love, the window regulators aren't the best, the box floor needs some love etc. trucking is not my primary business, I do residential excavating. I do haul a lot of my own material but I do also just have someone else haul it in if I need a lot, so yes a tri axle would be more efficient but I make more money running equipment so if it's not a deal breaker to sub out trucking now and then. I do however use it as a site truck a lot. If I were to upgrade it'd only be to a late 90's-early 2000 rd. I can't justify a granite even though I'd love to have one. I guess where I'm getting hung up is putting 10k or so into a truck I paid 17k for 7 years ago
