Yep, the only downside is the additional cost.
I've seen Azdel walls advertised by several manufacturers, and I'd like to see more of it. Laminated composite walls aren't much of a selling point on their own, though. A used RV on some dealer's lot could look great from the outside, with nice, straight, shiny, waterproof walls, and still be hiding a moldy, water-damaged nightmare inside of the walls. It's easier to see the damage with the delaminated and warped FRP/lauan walls.
It would be really nice to structural composite sub-flooring, just like in a boat, but that stuff costs much more than marine plywood, which costs much more than standard plywood, which costs more than OSB. So we get Azdel laminate walls over OSB flooring. Better than nothing, but not a lot better.
