Cargo door repair?

Hatchlift.com now has a backing plate kit. Fairly inexpensive too.

Good luck!

Those cargo doors are styrofoam core with a thin wood/plastic film,...this is what I did: The 6x8 3/16 aluminum plates cost me $20 to have cut at a machine shop, I used Sikaflex adhesive caulk for the adhesion, the screws were just to hold the plate in place while the adhesive cured. Been 3 years now, no sign of failure.

This is exactly what I did. Worked great too! The wood in the access door to our outside kitchen was junk. Drilled through the door with a high speed drill and super sharp bit so we didn't crack the fiberglass, and secured with larger bracket and stainless hardware. Not only worked to perfection but looked quite nice also.

When we brought our new Montana home the first thing that broke was the mount for the the shock, the wood is soft and the six screws just sort of fell out. My solution and it has lasted for over a year now was a product by System Three called GelMagic a non sagging epoxy adhesive. I took all the shock mounts off mixed up a batch of epoxy and was able to use the screws to hold them in place until the epoxy cured.
Now this stuff is expensive I just happen to be in the middle of building a sail boat and had some on hand. I'm sure that there are other epoxy based adhesives that would work just fine for less money.

Camping World has a hatch lift kit with a oversize backing plate that works great for this type of situation.

That's one way - tie the base plate to a larger plate...

Could you 'resurrect' the screw hole with hollow wall anchor ?
