Some of the more significant DIY repairs: 7 wire ground for the transmission computer to solve a shifting problem. Welding in a windshield hoop to keep the windshields from popping out and cracking, Replacing the mirrors, refrigerator, and hot water heater, Repairing the rear plastic bumper with fiberglass and rebuilding two hydraulic jacks. Also I eliminated the backup camera monitor and wired it to the TV
