Leaks and Rot

The picture in this post is from two different visits to the trailer. Some might be all over the place but I'll try mentioning what I'm looking at. At first I wasn't sure, but now I am. This camper will need to come off the frame and get back to having a solid foundation.

Sink drain fitting is leaking

Leaks again just above the
Wheel well, under sink

Green tape indication where
I might cut area inner shell to
Fix inside of outer shell.

Looking at where to brace interior
for off-frame support

Removed table support...

Table support screws were in bad shape 

Area of floor rotted out. I cut
fiberglass to see its condition.
Part of seating area is sagging

Could use a wire brush and repainted

Removed battery box and propane tank 

Removed diamond plate to look underneath

Many screws are rusted but many still hold tightly

Rotted floor by bench.
Is easy to push through here.

In some of the following pictures, you can see where many areas along the edges, the plywood used for the floor is not protected with fiberglass causing a lot of soft areas and rot.

Hard to tell in the picture but the
center part of the floor is sagging.
This is under the dinette.

Bad patch work under the bench
Big source of rot.

Now the trailer is covered up and tucked away for winter in it's storage space. Not sure when I'll get to this project. It will need a lot of work.

Cover isn't made for it but it'll do

Three buckles and nylon straps keep it tight.
