Nitro 1987 Toyota Land Cruiser
HJ75 Troopy Trakka Bushman

Nicknamed “Cobby Bob”

After an Australian Bushman we met during an outback trip to Old Andado Station, Australia
Read about Cobby Bob and Old Andado here.

This is the vehicle, I bought it from him, empty, bad motor, and needing refreshed, but overall great looking, really unique truck It was equipped as listed, had original “Roberts Lockers” Pre-ARB taking rights, cool. No compressor etc. Wanted to keep it in somewhat original state but with some modifications for reliability, drivability and offroad ability.
