For the last several days I have working on a new bumper for the popup. Started with trying to straighten the old one. Ended up making it worse. So I researched new ones, and most are made to hold sewer hoses and are made super thin. Needless to say expensive. My local metal supplier sold me a 4 x 4 square tubing for @$40. Had to notch around the two frame beams, so the back of the bumper does not stick out any further than the old one. (For the bed supports). Once I had everything fitting right, I was off to the welder. Also had the put on a hitch point for a bike rack which is welded to the bumper and the frame. Send more soon.
