I finally got around to cleaning up the trailer tongue of my Spartan Manor vintage camper trailer and wire wheeling revealed a big hole on one side! So I reinforced it with some big pieces of angle iron before priming and painting it.

This was a small project, coming in at about $42 and 5 hours.

I hope this helps on your own vintage camper restoration!
