Just to show the underside of the square tubing, and you will notice that there is rust hanging off the side.

In this next pic, you can see more rust, but the areas inside of the yellow ovals, is the rust actually being held in place by the glue that was put on to hold the aluminum sheeting under the floor joists. Even with all the water and rust, the glue still held. That is the pinkish stuff that can be seen in the lower oval. That's good stuff......Lol...

If you want to do something, you will find a way.
If you don't, you will find an excuse.

In this next shot, the step frame is starting to come together. I have some of the welding done, as seen in the corners with the light colored splotches.
![[image]](http://paddleupstream.com/mohorebuild/steprebuild8.jpg)
In the next photo, the yellow circles are areas that need to be welded yet. The two at the bottom, are not visible, because I have to remove the door in order to get to the frame underneath it.
Once the door is removed, these 3 pieces can be welded in place. I don't expect it to move after it's welded in place, and should be very sturdy compared to what the factory had in place.
This project will add a few pounds to the weight of the rv, but there will be other areas that we can remove some weight, for an over all net loss of weight. Yay......

Here is a close up of the area underneath the drivers side living room window where the rust is really bad, and I am removing some insulation. You can see in the picture, the putty knife holding the insulation away from the plywood behind it.
You can see right in the center of the picture the pinkish stuff, which is the glue. Even with all the water leaking down through here, the glue still held.........

Took a little break by scraping off some plywood from the fiberglass on the drivers side. It was still stuck pretty good, even though the plywood layer was kind of brittle. The darker areas are where glue is still holding a little bit of plywood in place. More scraping required to get that off.

I did a little more cleaning out today. I want to focus on an area below the drivers side living room window. This is where the worst of the rust is.
In the first pic, inside the yellow rectangle is where we will go a little closer.

In this next pic, you can see the different paarts of the side wall and the floor. The yellow arrows show the steel in the wall, which is 1" thick and 1 1/2" high.
The red arrows are part of the main floor. These are 1 1/2" square tubing instead of the rectangular stuff in the walls.
The green T is how they fastened the wall to the floor. It represents a bolt that came through the outside and just screwed through the outside steel and into the flooring steel. So, basically, the walls were just "hanging" on the outside of the flooring.

Now, this last picture shows a little closer this construction. The blue lines are the plywood that was glued to the outside of the steel wall framing.
The red lines are the 1 x 1 1/2" steel wall framing. The green line, is the 1 1/2" square tubing of the floor.
The yellow arrow is pointing to the interior paneling that is sandwiched between the floor steel and the wall steel.

Why would they build like this? It's easier, quicker, cheaper, and more convenient for the factory to assemble this way. Once the wall is completely assembled, it's a matter of a few screws and the sidewall is attached to the floor.

Got a chance to go out today and scrape off more of the plywood that was still glued to the fiberglass/filon. There were a few areas that did not have much water damage, and those areas were pretty tough to get the plywood off. The glue they used was still holding very well.
Drivers side right behind the drivers seat. Under the window still needs to be scraped, and has little water damage, so that will take a while.

And the drivers side from the middle of the rig to the rear....

In case you are wondering, this took over 4 hours to scrape what you see cleaned off, from front to rear.

Where has that motorhome been sitting at a bottom of a lake, that is some rust and rot going on.

No. Just goes to show what happens when a small amount of water continuously leaks over a long period of time.
The rotten steel is confined to a fairly small location. There are 2 side pieces that need replaced, about 5 feet long. Then about 3 floor joists about 2' long, and one about 4 feet. Only about 2' of the 4 footer was bad, but I cut it out anyway.
I have no doubt that the area that caused the complete rust out was leaking from the factory. It looks like the installer ran a screw in at the wrong place, backtracked, and then installed correctly. The hole was never filled and partially covered, so it went unnoticed.
The vast majority of steel rust is actually surface rust. A little work and the steel will look good as new.
