If selling the truck isn't an option, then keep it as your daily driver and use the Runner as your wheeler. This way you can beat on the Runner and keep the truck clean, which should keep your Dad happay as well. Also having another rig to get parts in is nice when your wheeling rig is down for repairs.

More than tread lightly. Leave it like you were never there, nor anyone else.
