Looks like a good truck to build a wheeler from, pre dented.
I would grab some bucket seats from a Cherokee and lots of mirrors and blinker lights if your going to wheel it much. Then think about armor and trimming some sheet metal.
A roll bar or roll cage should be on the list and a winch.
The box in the bed is nice and the Dana 44 is nice if it is metric ton.
Have fun with the build,
Ron
