I and several others I know used advantech 3/4". Less warping, moisture resistant, and very strong.

I called the Nyloboard company just last week for dealer info in my area. They were nice & sent me samples of 1/2" & 3/4" nyloboard (there is no 5/8"). The nearest dealer quoted me prices of $288 for a 4' x 8' sheet of 1/2", and $429 for a sheet of 3/4" 4' x 8'. That's not including the shipping (since they don't keep it stocked in their store) of $120 something. That's WAY out of the realm of possibilities for my pocketbook--I don't know about everyone else! I'm reading this with interest as well!

Isn't advantech tongue and groove? If so it won't break correctly on 4'.

Avantech makes 4x8 sheeting. I checked out the info on their website. Looks all right to me. I am using MGP that I coated with three coats of WestSystem epoxy and three coats of Defthane polyurethane floor finish.
Here is my thread with the post on flooring choices. Good luck!

Find the best grade of Douglas Fir Marine grade plywood you can afford and buy it. I was one of the first OSB reps in the Country and would not use that product in my trailer. Airstream used it back in the late '80's and I believe early 90's and lots of negative comments been made in this forum. PM if you want to know more. Don

Advantech sheathing is available in both square edge and tongue & groove. The tongue in groove is 4x8 until you slide the tongue into the groove.

With tongue and groove the long edges won't break on 16oc, you have to lay it long-waise to break on the floor joists. Make sure that you don't get tongue and groove.

my floor is 7'6" wide X 14' long

design is to place 1 sheet of sub floor at front 7'6"x3' w/2 round corners and at rear
(I have a frame support at 3' front and rear)

design is to place (2)3'3"x7' at center long-waise
(I have a frame support at center)

this will only create (1) T&G edge at center
(I plan to remove bottom of groove then glue top of goove to tongue)

Use good plywood, seal the edges with epoxy (West System is great), paint the underside with 3 coats of marine spar urethane , fix all the leaks in the trailer that caused the first floor to rot and you will not have to worry about it and you will have saved a ton of money that you WILL spend on other stuff you have not thought of at this point.

Yeah, we aren't done talking about plywood yet.

I used plywood that had the voids filled already, epoxied the edges, and used 3 coats of water based Verathane on bottom and top.

I recommend you use a meranti marine plywood. It is very flat, very solid, and has zero voids. The glue can pass a 48 hour boil test ( look it up on Wiki, the test involves boiling a sample for 24 hours. The glue must not break down. It passes 48 hours, but the wood fiber breaks down first. This brand doubles the standard) which will allow you to skip the coating stage without the least bit of guilt. The brand I use is called Aquatec and it runs me about $120/ sheet at the plywood wholesaler.

For underfloor insulation I use 2" ridged foam. The kind that is dense and yellow with a foil coat on the face and a blue vapor barrier on the back. I cut it very tight to fit and glue it to the underside of the sub floor. This gives a very high R value.

I will close by saying that advantex worked great as sheathing on my house. I would never consider it for a trailer though.

I had some floor repair to do and went with Advantech. 3/4 sheet was $22, but it wasn't the price that made my decision. My brother has built many homes over the years and this is all he will use in his subflooring. You can literally put it in a pool for a year and it wont change shape or size. Why would you want to buy high end plywood then add a bunch of sealants to it? Why not just buy a product that has everything you need in it already. My biggest issue when considering flooring and floor coverings is to eliminate the water issues. Reading a lot of threads it seems that floor rot is something that everyone will face at some point owning a vintage AS. So why not eliminate the issue by using a product that will never or not in my life time rot.

As for insulation. I used cans of spray foam. Andy from Inland was quoted that the Pink panther was what he uses, but to me why use something that will hold moisture if it ever got wet. His points were that any foam type will crumble overtime. I have one of the few '69's that they used spray on the underside of the subfloor that was in great shape when ripped up the floor. Heck that was '69 technology. I would think that Dow makes a better product today....but who knows.

I'm happy with my choices. I gave it a lot of thought. If you don't need the tongue you can easily break or cut it off. I also used several tubes of Vulkem around the edges. Edges I don't plan on seeing in my lifetime. . . .

Hope my 2 cents help....

Just thought I would respond to the comments on Advantech for flooring. I suspect that some may have confused Advantech for ordinary Oriented Strand Board (OSB). There is a world of difference in the production of the two. Advantech specifications for strength and water resistance make it far superior to commodity OSB and plywood.
How do I know? Well, I admit to working for one of the plants that produce Advantech. I can also tell you that I have frame up rebuilt two campers and now doing a third, an Avalair, frame up, similar construction to an Airstream. I would not do this much work without putting in what I think the best flooring, Advantech. The product undergoes continuous testing for meeting its rigorous specifications. Anyway, that’s what goes into my constructions. If you choose this, you must specify Advantech as there are those trying to copy (unsucessfully).
