Everything is coming together. Just about ready to drop the frame out and finnish weld joints. Then coat everything with Rust Bullet . Reinsulate and add skin. More to come....

When you mix the rust bullet remember to stir not shake,keeps the air bubbles down.

Basement Floor.. I got the frame all welded up and the top and bottom welds ground flat.  I got a good coat if rust bullet on it and will flip it over in the morning and coat other side.I  also coated the rear bulkhead 1/4 angle and the bottom part of my filler plate. I will rust bullet that once the too edge is welded in.
 As I have been in and under my coach doing this repair I see where there were design issues that allowed this to happen. I got this in 2014 so it was 24 yrs old then. But this rot had started much earlier. I see what I think is the main culprit for this. The fresh water tank has a overflow tube. It is a green looking ribbed tube. It runs behind the water heater over to the back bulkhead wall. If you look in your waterpump heater bay you should see it. The problem is when you fill your tank most of us wait until we have water running down outside just in front of rear wheel. Well I  usually do. So you fill water tank and off you go.Well that water overflow runs from the top of the tank and back to that bulkhead fitting. When your tank is full or near the top whenever you start to slosh water driving down the road or turn left water runs out that pipe it works it's way back and runs out. Where, right down the back wall and seeps down into your rear bulkhead flooring. Over all those years that uncoated metal got wet.
I am going to run a PVC  tube from that point down to the bottom below the bulkhead area. This is just my opinion after doing all this repair.  Here are some pictures! Because Everybody Loves Pictures!!!

That overflow pipe has been the topic of concern for this to happen for a few years. I read the posting years ago and changed the location after reading it but I never fill the tank more than 3/4 anyway so should not have been an issue to me..
Never needed a full tank as water is available anywhere, even if you have to buy the big bottles at a Wally world or so.

Yeah the overflow is poorly designed. As is much of the plumbing system imo. Should have been led to below the coach.

I have a question about the rusty surface on the steel bulkhead plate.  I guess that's what you call it.    Just what needs to be done with that surface ?  Apparently it doesn't need to be ground down to bare metal, then primed and painted. Because I'm sure if that was  necessary , Stump would be doing it.  I'm guessing that most of the coatings that are mentioned here will stop that rust from spreading and / or neutralize it. And if that's the case, how about the joints or seams that you can't get to. Which coating is better at penetrating into those areas. 
  The one I'm most familiar with is Ospho but even it needs to be painted for proper protection.    Living here in the Pacific Northwest rust is a constant concern cause it rains so much and although they don't use much salt on the roads YET , if you just ignore water intrusion it will still rust.      ESPECIALLY if you've recently spent some time on the Texas gulf coast where I hear it's some of the most corrosive conditions of any coast.    I now have some light surface rust on our coach that wasn't there before.
  Last year when we were there ( Mustang Island ) I sprayed some stuff on the undercarriage of the MH and the Jeep so the surface rust is no worse than before.  I am just super paranoid about any rusty situation advancing.
  So, I guess two questions.  One is , the best solution for established rust that your not grinding off and the second question. A solution for arresting surface rust.


  Or I could do like one of the guys on the Jeep forum.  Once a year when he rotates the tires then rattle cans the heck out of the wheel well area ( has since new ) and it still looks great.      Sorry about the long post.

I sprayed undercoating on the whole width of the angle iron, covering the Roloks also. The work to check torque the Rolok is a small price to pay to keep all water out of that side of the bulkhead

I have a question about the rusty surface on the steel bulkhead plate. 
Bob I did gribd and flap wheel the 1/4 bulkhead angle iron. It was then ospho coated which stops and neutralizes rust. Then it was coated with a product called Rust Bullet 
When everything is back together I will rust Bullet coat that area in back of the bulkhead.I then plan to something like Flex Seal sprayed along the back seam on the rear bulkhead angle iron.
In my opinion I think the cause came primarily from the fresh water tank overflow. It is at the top right backside of the bulkhead and water runs straight down onto the bulkhead seam. I think a good sealer along that seam will help tremendously. Jmo. Everything back there on mine will be sealed anywhere it even looks like a drip of water can seep in. :thumbsup:

Had some rust a couple of years ago in back of the front tires at the level of the basement floor,fixed and painted but then made some mud flaps to keep water away.

 I'll pick up some of the rust bullet stuff and give it a try. Thanks for documenting everything so well.

I put the basement back in today. I got the rear bolted up loose and finagled the front in  place.  I got clamps on it and started some divider wall bolts in holes.
I tack welded it in and then went back and finnish welded them. The old tube is being a pain to weld as it wants to blow out. I have a couple of horizontal supports that go in next. Ill get my neighbor Dennis to come and finnish the bottom welds. He is a pro. But it is all coming together. Not bad for a one man show....

Project has been going smooth. Everything is welded in and bolted up.I got the wetbay back wall metal coated with paint and the original fiberglass sheet reglued. Yesterday I cut opening for sewer hose and got waste and water tanks back in place . Now to get all the plumbing reconnected and the tank level wiring reconnected. I am going to build a new battery tray for the 8Ds that will bolt into the new framework. Hope to get that done next weekend.  Have to go trucking now
