My 2006 crew cab 4X4 with a manual transmission was stolen. It's difficult to find a 6.0 with a manual so I'm looking at 7.3 cause there's more of them available. Some sellers are claiming under 150k miles. I find that low mileage hard to believe. What should I look out for? Also I have heard the 4x4 from 99-02 ride harshly compared to the 04-07 models. Trying to stay away from car dealers, people who lifted their trucks. Chips on the 6.0 are a problem IMHO I don't know enough about the 7.3 to have an opinion. Any advice greatly appreciated. Don't think that I would ever be happy with an automatic transmission so that's not an option till I've exhausted all other choices. Not a fan of Dodge trucks however it's way easier to find a manual transmission there. My dad had a 96 extended cab DWD with a 5 speed, he installed a hi-lo Gear Vender. Awesome drive train the rest of the truck not so much.
