It appears the wheel choices are endless and possibly change from year to year. Can't speak to the accuracy of these photos as they are just lifted off the INTERWEB.

my brother-in-law had an exact copy of this yellow one, he beat the stink out of it.

FWIW, I have an MPC 4X4 version of that Truck somewhere in my stash. I bought it a hundred years ago...well...maybe not that long ago....at a swap meet. The instructions show some wacky 4x4 decals, but were not included in mine. Have no idea if they were copies of the actual truck or just something the art department thought up. I bought mine for next to nothing, I do plan to build it someday.

I have no idea how capable of a 4wheeler they were, but I always thought that Mitsubishi was a pretty solid manufacture.
