They fit. Just wish it came as a double pack. Chances are both need to be replaced at the same time.

I bought these for my travel trailer, to replace the stock bumper plugs which were made of hard plastic and I had to duct tape to keep in place. These stay in the bumper without need for any tape!

It was very easy to install these plugs and were very easy to fall off or be taken by passerby.

These stay in place unlike the original caps provided by our RV dealer which flew off on our first trip. Some people have complained about these being hard or difficult to insert into the bumper tubes/ Come on people a little pressure is required to hold these in place and then when you depress the center in it adds additional pressure locking these caps in...... no more missing caps unless its from a person looking to replace one of their own missing caps..........of course we all know that never happens
