More than likely, the particle board is glued down with somethings like liquid nails. If it's bad, you need to scrape/grind it out and replace it with something. You'll find lots of opinions here on what to use and how to prep and install it. I did my floor with 1/2 marine plywood saturated with 3:1 epoxy resin and glued to the fiberglass with 1:1 thickened epoxy glue. Other folks are using less expensive plywood, other types of surface coatings and different glued. YMMV

The liquid version of Barkeepers Friend. Rinse well. I only used it on the outside.
EDIT: on the outside where I could rinse with a hose and sponge. Our Uhaul is similar to your Burro, inner fiberglass shell

Well I'll get in there and see if I can somehow pry it off in chunks somehow. Can't imagine grinding it down!

Probably too late now, but I don't see your post giving the reason for wanting to remove the floor. Pictures also help those who would help you.

Question Advice needed on next steps

So, I finally found the "sub floor" in my burro! Got the 1/2" ply up no problem. Then saw that there was maybe a 1/4" ply sandwiched under the fiberglass liner. This is completely rotted in some areas and solid in other areas. Now, I have to figure out where to go from here. I hate to rip up the whole floor if some of the wood is ok but it's going to be difficult replacing it in uneven sections.

The factory floor is plywood sandwiched between fiberglass. I see the opinion of many here is that the floor only goes bad from the top down, and that makes plenty of sense to me. But if that is the case, why would the manufacturer have bothered with the trouble and expense of fiberglassing the bottom of the floor?
My main reason for asking is if I wind up replacing our floor is there anything you do to the new floor besides maybe a coat of paint to protect from road spray?
