Lots of people are looking for a vehicle they can take to the local dump for grass, leaves, tree limbs, etc. and they don't care how they ride or even how fast they go. And, they look really cool. I am betting if I had a hundred of these modified trucks they would sell very fast IF they fit nicely in a standard garage.
I have more ambitious plans for my short wheelbase.. a power generator on one side, a toolbox on the other, a swing out engine hoist in the bed, air compressor, maybe a welding and cutting setup so I can do whatever I need at the salvage yards. Gas tank behind the seat for better management of space, etc. Its all about fun!
