I spotted a variation of this idea for a grab bar at a Chicago RV show.
I bought a shower-stall grab bar at a home-improvement store and mounted it vertically next to the door inside my RV, so we can grip it when exiting. The inside of the door frame is metal, so the attachment is secure. The one I saw at the RV show had a custom twist, making it a bit more useful, but I couldn’t find the name of the manufacturer, so I purchased a standard stainless-steel wall-mount grab bar instead. With our grab bar right inside the door, we feel very secure walking down the narrow RV steps, especially at night. Note: Do not install this grab handle unless the RV has adequate backing.
