I'd try to determine *why* they are pulling away before doing a fix. It is possible that water is getting in there, making the wood behind it go bad. then, as mentioned, if the wood isn't bad, you may need to use bigger screws, or use something to get better bite. Finally, I'd be using silicone or similar both between the gutter and the trailer wall, followed up by a bead of it along the top, after its all in place.
Bad wood due to wicking screws would be my bet and unfortunately the fix might not be simple depending on the damage. The area affected is that area I call the triangle of death and HIGHLY PRONE to leaks since it's that area where water can pool on the roof at the corner.
I suspect there will be significant damage in the wood making reattaching the gutter/awning rail very difficult. If you can get at least some "hold" from the screws where the problem is using 3M 5200 adhesive/sealant between the gutter/rail and the trailer side might do the trick, but this is a "PERMANENT REPAIR" and any future attempt at removing the gutter/rail could damage the trailer side.
