just out of curiousity-did you see evidence of the ants inside before you found the nest? we are having tiny little ants that are either just coincidentally happening or i wonder if we are harboring a nest somewhere...i have bait traps inside and also outside our current location...

I only spotted in ants in the rotted sections. Strangely, they appear to be gone now. I did not treat the area with anything.

Rivet wood floor damage fix

Something an old timer showed me on repairing sections of wood rot while keeping weight down. Cut out the bad wood, no additive will make it like new or usefull and it takes less time to do it right. Now cut 4" X 4" of the same thickness wood to attach underneath the good floor with Elmers waterproof wood glue, very cheap and once sets up (24 hours) like steel, clamp the pieces under the edge with 2" attached to the wood and 2" showing. Now after a day you can drop in the new floor piece onto the supports. Use the wood glue as before, and if you like run some flat head stainless screws into it where the supports are to pull it together (after drilling holes first so the screws grip the wood underneath not the floor) . Just like patching a drywall hole you can now add a filler on the seams if needed and you're done. Be sure to use a good grade of plywood or some hardwood plywood.

Sounds a lot like what my service manual recommends. So hearing that you've done this before makes me feel comfortable with it. Thanks so much!

Update...with new questions and concerns.

I have discovered where water was coming in in all the areas, and I am working to repair and seal those areas. However, after removing subfloor sections, I discovered some pretty rusty frame sections under the rotted floor. I've attached some pics (quick iPhone shots, sorry.) Here are my questions regarding that...

1) Is this level of rust acceptable? There are signs of deeply pitted areas, but it still feels solid. How do I know?

1.) Now that I see there is rusted frame sections, should I be concerned that the rust goes beyond what I can see? Should I go ahead and remove the belly pan to see what's going on before I invest more time and money on restoring/renovating?

3.) Assuming for a second the rust issue is contained here and is not a project killer, how do I best treat and prevent it?

Any rust, is too much rust.

Clean all the rust off of everything you can find. Then you can coat it with underseal that comes in spray cans.

Only you, after cleaning up the rust, can determine if that part is still ok to use.

I would suggest that you drop the complete underbelly and inspect for rust.

Assuming other parts may not be rust, is a huge risk, as a major part of the frame could be bad.

Only way to find out, is inspection.

Trailer body and Frame

I have a '74 Argosy with some minor floor rot near the entrance door and in the bath. While doing the repairs. A question came to mind. How is the Aluminum frame of the body attached to the steel frame of the trailer? I can see that the floor is attached to the steel frame and there are sheetmetal screws that attach an aluminum channel in which the floor is sandwiched. It looks like the ribs (aluminum frame members) are attached to this aluminum channel as well as the inner and outer skin. Is the floor wood an intergral part of the frame structure? If it is rotted in too many places will the body become detached from the frame?

I have used Alco Gutter Seal on every seam of the exterior, and have not had any problems since. It produces a finer bead than Vulkem does, IMHO

That rust doesn't look too bad. If it structurally sound , I'd just POR 15 or similar product it and be done with it.

As is, if you use enough paint to get the bottom edges of the rusted outriggers it will glue the aluminum to the iron - if the main ladder rails don't appear to need immediate care you can fold that wrap section down like a flower petal and care for the outriggers - just have to have the will-power not to scratch any other itch :/

I have cut out larger sections of the floor and will post pics of what I have found. Hopefully this will give a better idea of the rust situation. My initial gut feeling based on the feedback I've gotten so far is that it's just surface level. There are some areas that seem to be corroding deeper than that, but only in small spots....pics coming in a few hours.

Here are the new pics. I cleaned up the areas quite a bit, there was a ton of sand and dirt. Like this thing had been backed into a beach sand dune. Is this normal?

Wow. You really don't want to hear what I want to say so I will say this... Looks like your timing is perfect, just enough damage to warrant refurbishing but not enough you will be splicing in new metal.

My intent from the beginning was to refurbish it, but that didn't include doing major frame work. What I now want to know is does this look like I need to deal with frame repair? Is this much rust normal for a 30 year old Airstream?
