I know the hardside flooring is made of "Structurwood" OSB (oriented strand board). That doesn't concern me because I used to sell that product when I worked at a building supply company.
My concern is this: When I went to the local Flagstaff dealer, I got down on my knees and looked up underneath the A-frame trailer. You can see the flooring from underneath. It seems to be coated with black sealant or paint of some sort, but you can still see the individual chips of the flooring.
I would think that over time, spray from the tires, salt, mud, etc. would cause the flooring to delaminate.
I was hoping that my fellow campers would be able to shed some light on the matter.
Thank you in advance.
