I have made a trailer plug storage from a old plastic snaptop Spam container. I have cut access for the main wire bundle and four small holes for two wireties to fasten this 'storage box' to the jack post. A fifteen minute project after you eat the Spam.
First is the empty box on the post.
Second is the box with the plug inside. Yes I see the hole too.
I'll cover it with electrical tape before I paint the whole thing black. You, should you choose to do the same thing, might be a bit more careful.
Now the storage box with the lid fastened to protect the plug from the weather.
I will add some silicone over the holes for the wireties. That way the only opening is around the wire bundle and should be made as small as possible.
I got this idea from a satelite dish installation done for me twenty years ago. If you wish to use this idea, please feel free to do so.
