Board floors , not plywood ...

Good points for both Plywood and boards , or even foam ... Guess it’s up to the builder to choose ...

FYI, I’m only trying to promote different ideas here , so don’t get mad at me if you don’t agree... Simply post your views for consideration too ...

Me too. That is a lot of my post. It make people think outside the box.

Althought not for this topic, I agree not to agree at times. Isn't this what it is all about....exchanging ideas and thoughs?

Yeah , If we all thought the same , nobody would be thinking ... And we’d all likely still be building wooden trailers ...

I apologize for my enthusiasm , but I just love the idea of building a comfortable , usable trailer for under $1000.00 ... And not requiring a shop filled with big tools to do it ... and then , there’s "the Ballast" ...

I still don't see a better method than ply treated with epoxy or the mix.

[GPW]

Best so far eh , but treated OSB isn’t so bad either , but even Heavier ...
We have to get the Marine plywood... That’s very pricy , but if it lasts ... We know the foam will last a very long time ... can you imagine a hundred years from now and all the Vintage Foam trailers on the market , still camp-able ...

Simple construction.
Lightweight.
Protected underside.
No wood rot.
Insulated floor.

That is close to what I did. My floor is painted canvas on the bottom with 2" EPS and FRP on the top. Very light, warm and will not rot. I would have to say I think it have about the same flex as 1/2 plywood. With metal on the bottom it would be like 3/4 plywood.

You guys are definitely on to something here ...

And with a little looking around we can get foam with greater density , making it even better as part of a composite floor ... The Blue /Pink foam we usually find is ~ 2 lb./cu.ft. Imagine how much stronger 4 or 6 lb foam would be...

The Dow site has lots of information ... Check out the "deckmate” foam ... http://building.dow.com/en-us/products# ... C0%7C0%7C0

Price point for enough sq ft becomes the next question

[GPW]

Well considering a really good sheet of specialized plywood might cost over $100 .00 now ....maybe somethng Better is not too much more ..... hopefully ...

did Y'all forget about "THE MIX"? Treat the floor plywood with it as well. should be good for go then.

[GPW]

CL, True , but some people ignore the floor .. thinking the ply alone will survive ...
But then again , it’s the nature of wood t take in water ...all those little tubes .... capillary action , working against us ... Actually OSB is better as a wood product, because the tubes only run so far , not full length of the product ... Still looking for a better floor materiaL , one impervious to water ...

Not foamies, but two examples of the sketch above.

.063" aluminum riveted to frame, 2" extruded polystyrene, lay flat/no glue vinyl flooring.



.050" aluminum riveted to frame, 1-1/2" extruded polystyrene, 1/4" oak plywood flooring.
