Red Hound Auto Bumper Plug End Cap Square 4 Inches Vented Cover RV Camper Trailer Single

This item DOES NOT FIT STANDARD 4" square rear bumper! I had to grind the edges down quite a bit & then hammer it into bumper. My motorhome rear bumper is 4" square as this item claims to be. IT IS NOT. By having to hammer it into the bumper, it is now impossible to remove. Luckily I put the cap that came with my RV on the end nearer the sewer hookup so I can still use the bumper for storing the sewer hose, as was intended by the manufacturer as are most RVs.

These were difficult to use. They're made of a hard plastic that did not fit well in our bumper. My husband tried carving off some of the product to get it to fit better. One fell out while we were on the road. The other he hammered a whole in trying to force it to fit into the bumper.

Just note this is only for "one" I was assuming it was for 2 as most people would want a set for their bumper. I haven't installed it yet but it is very sturdy. Looks like quality but for 8 bucks for one it is a bit overpriced in my opinion.

Did not fit my Winnebago Minnie Winnie even though size is the same. Had to pound it in, lost a little rubber on the inside. Now it won't EVER fall out, downfall is that it is also not suitable for removing the sewer hose no more. Luckily it was just one side that needed to be replaced.

This cap is well made of hard plastic, but woul dnot fit in my RV bumper, it was about 1/8 or 1/4 inch to large
