Rob,
If you haven't opened the outer shell of the trailer, you can try to find the leak. Close the doors and windows, maybe remove a ceiling vent, and pressurize the trailer with a leaf blower or similar blower sealed into that vent. Go over the outside with a soap suds solution looking for bubbles. If you find one, keep looking. Nothing says there can't be more than one leak.
I'm free of prostate cancer for 5 years now.
All men over age 50 should get an annual PSA blood test. Mine had a low reading, but the yearly jump was significant. The biopsy showed cancer just entering the aggressive stage. Dr. Hackenslash removed it.
The isulation looks good. This does not appear to me that the leak started on top, but rather from the bottom up.
For the floor that's just rotted out, you'll have to remove it.
For the floor that's still got something left, consider using a product like 'grit-rot', which is used for plywood coring in the boating industry. It's a very thin epoxy that's specially formulated to penetrate plywood. You drill small holes in the plywood with a 1/8th inch bit every inch or so, and then using a siringe, inject the epoxy. It will evaporate the water let in the plywood and firm it up stronger then ever.
No doubt - I wondered were all the trailers on seasonal sites near the rivers around here went that flooded last year. I still remember the pictures of some CG's with 3-4 water and the travel trailers just sitting in it.
I'm sure many of them were totaled or ended up in auctions.
Good luck.

I agree with dodgeguy,looks like it could have been in a flood,look for signs in other places for muddy water stains,battery box,frame rails,look inside brake drums,just a thought,good luck,my moto "enough time and money,I (you) can fix anything!"

I think a flood would show alot more staining in the underbelly. There was no water damage to the interior woodwork. Frame definitely shows some rust but nothing substantial yet.
Grit Rot sounds like fantastic stuff, great tip. It's just one big lego set. I'm going to keep pulling things out until I hit solid wood. Too late for the leafblower I fear, good thought.
I had parked nose up to keep draining water off the front. I tilted it down after work today and got a good drainage test in, due to a days worth of rain. Window was leaking in the front right but it was running down the aluminum and not really touching the wall members at all. I removed the inner window ring yesterday so it may be a new leak. Running some heat on it now to dry everything out an i'll cut open the fabric underneath in the back to inspect the rest of the joist. Hopefully the rebuild won't weigh too much beyond original specs, it will be hard to put such flimsy framing back in.
Thanks for your thoughts
Rob
Edit: First real project on this thing was bearings and brake adjustment. More cobwebs than anything else...
