Sliding siding and broke water support band

[DDEVO]

Hello Everyone,

We've been loving our EVO the last couple of years. This forum has been a huge help in many regards.

I've went to visit out trailer a couple times this winter at it's storage area, and found that it has some sliding coming off the side of the trailer. From the pics you can see, there evidently hasn't been much in the way of water damage, and there also isn't any sign of external damage that may have got theses loose. They are at the lower side, and there was a leak in the sink early on over our first few trips that I found by water slowly dripping down this back area from the bathroom sink. I'm guessing that loosened the siding adhesive a bit? Any thoughts? Especially in terms of repairing this? We are out of warranty, and I'm rather handy, just don't want to mess anything up before I jump in, as getting parts isn't easy!

Also, for some reason the metal band broke that helps support the weight of the gray and black water tubing. I drilled two new holes in hit, but have came to see it is not easy to remove the old nut and screw head(that is again st the tube with no clearance!). Has anyone ever fixed any of these in a semi-professional manner before?

Thanks for the advice, and hope everyone is doing well! :-)
