3 layers flooring concept & replacement

Hi guys
Working on the Avion we know that eventually will get to remove the sub-floor in the livingroom, Bathroom and basement area.
We are aware that the floors were the 3layer style (plywood/styrofoam insulation/plywood).
At that point we are not sure if we should stick to the original concept (kind of love the idea of insulation) or just 1 solid plywood airstream Style.
Any inputs will be appreciated.

Hi Perry
Not 100 % how much will need to be replaced but we will remove the floor in the livingroom and bathroom for sure.
We now for a fact that the area under the slide out is rotten and we can see from the basement are that a lot of the lower layer of the bathroom is also gone.
But we are still far from give an accurate % of the floor damaged due the water.
Never saw the 3 layer floor concept before

If both layers are rotten then replace the whole thing. If just the top layer is bad then patch. How thick is each layer?

according to here:
SILVERAVION :: Maintenance

The Avion floor is fabricated in three layers. The bottom layer appears to be 3/4" thick plywood. The center section is Styrofoam and the top section is 1/2" plywood.

That is not the case on ours, we have 1/4 plywood+1 1/2 Styrofoam +1/4 plywood, now that is 2"sub-floor and with a big insulation, I bet that winter camping on this unit wouldn't be that bad!

Hey Perry just noticed that the last post just made us RivetMaster is there a ceremony? or we should just consider our godfather in our revited initiation?

I would leave it the same unless you can think of a good reason to change it. "if it is not necessary to change then it is necessary not to change". The older I get the more I use some old sayings. I like the sandwich concept personally. Did they use any adhesive between the insulation and the 1/4" plywood?

Hi Dan it is good to "see" you!
Totally agree with you on the unnecessary changes, but this is a kind of mandatory.
A lot of parts of the wood of the 3layer floor are gone!
The worse so far is under the slide out area, not sure for how long this trailer was neglected, but is a very sad scenario.
Will try to post some pics of the most know affected areas in few mins.

Yeah that looks like a mess. It is hard to get an idea how all that fits together. I don't know how you are going to splice in new subfloor with the way it is constructed. If it is 1.5" of foam you maybe able to use a 2x4 to splice in new pieces by putting it where the foam core was a glue and screw it to a new piece of subfloor. You should be able to make a sandwich with new foam and plywood.

Yes it does looks messy, but is not that bad. We saw worse floors in some threads before
Well, at this point we are getting to the conclusion to do a total subfloor removal.
Anyone familiar with Avion flooring? We understand that the Avion's shell is bolted to the frame and not to the subfloor, so subfloor removal shouldn't be that bad?
Any one that has removed floors on an Avion around

Do all three layers sit on top of the frame?
