This Jeep loves to be off-road! One owner. Driven mostly stock until 2016 when Bruiser Conversions out of Clearwater, FL did the engine swap and other major mechanical work. We then had it shipped to Africa for a 2 year drive (36,000 miles) in southern and eastern Africa. You can see the adventures at where we posted our tour through Africa. This Jeep has been amazing! Selling it because our needs have changed as we continue to live on the road in the US. Clean title, registered in Oregon. Summer 2023 Jeep located in Nevada and Arizona.

Known Problems: Air Conditioning works great, but the re-flash of the ECM by Bruiser deleted the thermostat at the expansion valve, causing to occasionally ice up. When this happens, shutting of the AC will cause it to thaw quickly and work again in minutes. Cosmetic damage to the fiberglass top under the Gobi Rack at ladder and one other place on top edge and one spot on the body near the fuel fill.
