End caps on rear bumper come loose

Ok, this is a plumbing related question, I guess. The end caps on the rear bumper come loose while I am moving. I am afraid that sooner or later one will come off and the sewer hose will come out on the highway. It is a new trailer and the hose actually fits pretty snug so I am not sure how the end caps are coming loose. Is there a better method for securing the caps to the bumpers?

They will come off eventually.
I found mine half out more than once so I drilled mine and put a safety pin thru them.
I made the safety pin out of #9 galvanized fence wire.
You can buy the large safey clips at most farm stores or even a well stocked
hardware store. Think of a large version of the safety clip that comes with your
receiver hitch.

If you're totally baffled, I can take a photo and post- that is unless someone else
beats me to it!

Do you have anything else attached to the bumper...spare tire or bike rack? The end caps work their way out with flexing of the bumper.

I've attached mine with a couple of SS screws but I don't use the bumper for hose storage.

On one side I used self tapping sheet metal screws, 2 in opposite corners.

And on the other side I added a small bungy cord so I could still get to my hose.

One of mine came off on the way from the dealer when we bought it. I use black electrical time on them now. I'm keeping it one more season beforing trading it in for 5'er, so I don't want to drill anything into the bumpers for a 4.99 part

I have a plastic bag scrunched up as a filler between the cap and bumper. But I've also found that turning the cap 1/4 turn will help find the tightest fit.

WirthCo 30000 Black RV Locking Bumper Plug $6.56 each at and probably available at other places, too. Put them in, then push in the center of the cap to expand the edges and lock them in place. My OEM caps kept coming out, too, but these have eliminated the problem.

Smile End caps, useless

I have had many, many trailers and none of them came with end caps that worked. It's one of those things that look nice on the sales lot but are hopeless. I silicone one end on and I throw the other end cap away. Then I drill a hole in the top of the bumper near the end and simply drop a 4" nail through it. It doesn't look that pretty but I have never lost a hose and it is always dry when I go to use it.
