I've been going up and down my 2012 Jayflight a lot lately to do some roof repair. Every time I climb the ladder I see the upper anchor points and it looks to me like the plates are slowly pulling away from the trailer. I want to remove the existing screws and install larger and longer screws. You can see in the closeup pic how the plate is starting to bend. The lower 4 mounting plates are perfectly flat against the trailer. Anyone know how "beefy" the studs are that these screws are attached to? Or how the wood blocking is configured on the back wall of these trailers? I'm not a big guy, only 170lbs, but I'm afraid to use the ladder any more until I reinforce it.
I have a '12 model too and my ladder has been fine but does flex a lot. A little unnerving but I still trust it but I go up and down rather gingerly. If you don't trust it, brace it as a rear ladder is nice to have.
Your idea for the fix sounds soild. However I believe you will need to remove the existing ladder and increase the hole size to the diameter needed for the new screws, and of course as stated before use the same length.
I carry a folding ladder to access the slider roof then up onto the roof. Well, because I'm a slightly larger man.
