Mostly good advice so far, id look at tacos and tundras and find the lowest mileage one as possible under 100k. Don't be in a rush to find the right rig, but when you find a deal jump on it. As far as offroad mods you could really go down a rabbit hole, but first put some aggresive A/Ts or muds on it. Then a good suspension (icon,king,radflo). Keep recovery gear in the rig (chains, come along or winch, snatch block, straps etc. Everyone will eventually get a lemon, it happens, but far and away Toyota has a very good reputation for a reason, same cannot be said for chevy, ford and Chrysler.
