Rubber bumper ends

I made pins from stainless steel wire.

I bought "locking" bumper caps.....basically you put them on and then push in on them and they kinda wedge themselves into place.

Back when we had a 4" bumper to cap, I replaced the standard caps with a pair of these insect resistant caps. As well as keeping bees, etc, from nesting in the bumper, they stay in place very well and have to be squeezed to release them.

Here's an easy solution I found. It works very well, doesn't cost much and takes no special modifications on your bumper.

I went to Wall Mart and pick up a bunch of small (the very small) bungie cords. I wrapped one around the bumper inside the front-to-back frame. I then attached two, one on top and one on the bottom to the bungie cord and wrapped around the end of the bumper keeping the cap from ever coming off.

On my previous camper, I lost 3 of those end-camps while traveling. I finally got smart and started doing this. I've never lost another one. The only problem, every year, I need to replace the bungies because they do loose their stretchiness after exposure to heat, sun, rain, and cold. But this works very nice, no modifications, and doesn't cost but a couple dollars for the bungies. Here's about the best photo I could find. Hope this makes sense.

If you use the black bungies, you'll never see them, and put the clips on the side you can't see from behind.
