When you're talking about mushy floors, I'd be willing to bet that 99% of those floors affected are using OSB! OSB and Luaun are a set-up for a failing floor.

I'll take that bet, any amount. Considering how long OSB has been around, my guess would be that the vast majority of floor problems in RVs have occurred to a plywood floor. And still do today. I couldn't begin to count how many plywood roofs, floors, and walls I've repaired due to rot. Way more than OSB. Water is the most destructive force on Earth. There isn't much of any common material that handle being continually wet without losing structural ability.
PS Lauan is a plywood and, when used to its design parameters, is every bit as good as anything else in the same application.
Agreed. People are very misinformed concerning OSB because its very convenient to group it into one large category.
OSB comes in a lot of different variations, initially there were problems with the 1st generations of OSB however Advantech and other OSB products are superior in many ways.
Lauan plywood is not a bad product either however it is often misused.
It is inexpensive and easy to work with however it is not the cure all universal product that uninformed installers try to make it out to be.
It's all about using the correct product for the application.
Hallalejah! Somebody else who knows what they are talking about! And realizes there are no absolutes. The next round of Guiness is on me.
And I'll get the next round!
I think some folks, like mentioned, are thinking about flake board or particle board, when OSB is used. It is not the same.
Lately, I've even seen the treated blue sheet goods used in exterior wall sheathing, a product that is supposed to mitigate cavity wall moisture. IME, if the wall of a structure is built well, there won't be any severe moisture issues.
A lot of these products are based on consumer perception of issues they will never see. I think the same could be said of floor problems. As long as water isn't leaking onto the floor, into the walls, or flooding the interior, nearly all RV'ers won't have a problem.
As to Ms. Wood Glue's take on material science, she should look a little further than Lance videos and market-speak. FWIW, I have a very nice yard barn that has unpainted Luaun doors. I did spread some leftover varnish on them five or so years ago. Since then, they have been directly exposed to the weather.
