My first welding project with my new Lincoln 125 MIG welder
These stout steel rails will keep rocks from denting the body when rock crawling.
I have to give credit where credit is due...this design was taken from a guy named MJ Dan who I saw on the NAXJA forums

3/16" wall tubing can take some serious abuse.
Rails solidly mount to the frame and the pinch weld on the cab underneath the doors.
