Need some design opinions. I'm putting together a new set of front and rear bumpers for my k5. They are going to be made out of 3" steel tubing each bumper will be 2 tubes, one over the other. I'm trying to decide if I should make them straight, or angle them back on the sides. I'm looking for pics of bumpers set up like this. Did a search and only found single tubes or prerunners made of smaller tubing. I just got all the steel to do this and set up my front receiver, as well as the connections to set them up as my air tanks. I figure if I use the front ones for the front tires, and the back bumper tubes for the back tires I should have enough air for at least one air-up when going back on the road.
