I,d look at the screws they used, if there rusty? remove and by stainless ones. one size bigger. and put a dab of a good rv sealer in the hole and on each screw.
These are screws under the drip rail (covered by it), the only way to get to them would be to pull it all off the RV. I don't think that is going to happen.
I will post pictures.
The screws are under the vinyl snap trim. Typically they install the roof membrane and let it hang wild over the side, then screw the gutter or awning rail over it. If they actually used butyl tape is hit and miss. Then they seal the top of the gutter extrusion to the roof membrane with non sag roof sealant, take a razor knife and cut the excess roof membrane off at the bottom of the gutter, and snap in the vinyl. The vinyl snap trim is not water tight by a longshot. If the gutter gets debris in it water is getting in that snap trim and to the screws.
Most manufacturers do not caulk the bottom edge of the gutter or awning rail to the sidewall. This lets any water that gets behind the snap trim and to the screws run out between the extrusion and the roof membrane in theory if it gets through the screws. Once the screws corrode enough chances are its getting inside the wall. Once it gets in the wall that is how delam starts.
Pull the snap trim, replace all the screws with ss screws and pump a good sealant in the holes before you run them in. Then remove all the sealant from the underside of the rails at the sidewalls. New snap trim is cheap.
