The screws that were in there were already larger that the rest of the ladder screws. I assume someone stripped out the holes and put in larger screws as a "fix". I want to repair this and reinstall the ladder bracket in the same spot.
Any ideas?

The ear plugs must be the porous type with open pores. Some ear plugs have a film converting the foam to prevent them from absorbing dirt, sweat, ear wax etc. Also prevents absorbing epoxy.
Larry wrote on Thu, 13 April 2017 08:05Dale Ropp has given several presentations at GMCMI conventions about the use of fiberglass for building and repair of GMC related stuff. One of his techniques for repairing holes like yours is to soak ear plugs....you know the type that you put in your ears when trap shooting.....soak them in fiberglass resin then stick them in the holes. They will try to expand to their original shape on the inside and outside of the hole. After the resin sets, just carefully sand off the outside flush, paint and redrill the hole. This technique puts a fairly big bung of cured resin inside the hole for support without having to take the inside of the coach apart. I've tried this on my coach were the screws pulled out and was difficult if not impossible to get at the inside to mount support. JWID

Bryan, I used "Rivet Nuts for Plastic and Composites" from McMaster-Carr.
https://www.mcmaster.com/#rivets/=176j0fo
Use some epoxy to seal the head of the RN, and if the latter has a misalignment making the leg not sit right,
then bend or shim so as to not have any pull out force on the RN.
What I did.

Or you can use well nuts as shown here.

They work well and are self sealing. I have them holding the top of my ladder.
You will have to open the holes to 1/2” for the large screw/bolt that you will be using. They are very strong.

Ahh yes. The old "I discovered more syndrome" I can relate. My sympathies.
Haha...you don't know the half of it.
Yeah - in old house restoration it''s called "the mushroom factor". I my shop it has been dubbed as "the ultimate project creep."

This is a great idea. Not to hijack the thread, but has anyone tried doing something similar with the holes for the clearance lights? I've got a few rear clearance lights where the screw holes have gotten a little too large for the rivet nuts that I'm using on the rest of the coach, but still too small for the next size up.

Have
Not tried
It myself. But dale's presentation at chippawa falls stuck with me.
If the ear plug is big enough for the well nut hole it should work the same. Dale suggested for larger holds, use a sponge soaked in the epoxy.
