🚐 RecPro 2 RV 4-inch Bumper Plug End Cap Cover with Tabs - Black, Made in America for Camper Travel Trailers Review

I fit my 4 inch bumper perfectly. I ordered a cheaper one from another company that was exactly 4 inches and didn't fit in the bumper. This is a little under 4 inches and has small protrusions on the side that fit into the bumper recess. Great fit. Worth the higher price.

The dimensions given are incorrect. The opening in my bumper (internal measurement) is just over 4 inches (4 1/16 inches). They fit perfectly in a 3 3/4" bumper as they are just missing a 3 3/4" hair in the part that fits in the bumper. So they just fall out when I try to put them in. They should be listed as "Rubber Bumper End Cap for 3 3/4" ID Bumpers".

Well made but much stiffer than expected. If your square channel bumper is a little crooked, as it usually is, they are not very forgiving. I had to use a hammer to get them a better fit and still I'm nervous about them falling out so I pack something inside for a while to keep my drain hose secure in case they fall out. decide to leave the site somewhere along the way.
