I rolled it at ocotillo wells over a huge woop section. I saw it last minute tried to swerve out of the way, but was to late. The back wheel caught the top of the woop and rolled about 3 or 4 times. all that was damaged was the top of the buggy, exhaust, and back wheel. I don,t know what model welder that is. It's my buddy that welded my new frame up.
