We had one on a job site made by Diahatsu and it had an ity bitty little turbo diesel was 4wd with full push button lockers, front, center, and rear. Suspension sucked but we beat that thing. This one nutty guy was flying along in it, came up to a rut in the asphalt and locked up the brakes and as the front went into the rut it did a forward flip, awesome.
