DH is concerned because our Coachmen Mirada has no bumpers

I have not seen official bumpers on any rig. You can have one fabricated by a good welding shop. I did see a rig one time where the owner had a hitch receiver welded to the frame on the front and had a fabricated bumper with lights mounted to it. He could remove it to wash behind it, etc. I have considered having this done myself.
