Robust bumpers on RVs, the last factory ones I seen were dropped around the 1970s. But, I do agree if you keep the load on the bumper from bouncing independently from the bumper, it will last longer. I had a 1996 park trailer on coastal property. I repainted the bumper yearly and sometimes once every 2 years. No matter, it rusted, some clear through the bumper in spots by the 10 year mark.
