Flooring replacement

[Mikedriggers]

Hey guys and gals, I could sure use so help. I bought a 2008 Flagstaff Classic Super Lite...33' w/ 2 slides knowing I had alot of work ahead..didnt realize how much. Trying to remodel so I can hit the road on a National Park tour.
Floors are rotten so I'm starting there first to keep from falling through..(did I mention I'm living in it while doing the work)? The floor seems to be thin, like 1/4" plywood with linoleum flooring. The flooring seems to be glued and also stapeled down. In trying to pull up the old flooring it is pulling up a layer of Styrofoam insulation with it. My questions are...
1) is there an easier way to remove the old flooring than pulling it up in pieces..this could take me months.
2) once I am ready to put down the new floor can I upside to 1/2" or more and slide still work. ( did I mention I am a 300#+ guy?)

Ok " Super Lite " means the RV was built using the minimum of materials to keep the weight down .
That would mean frame, floor , walls , insulation, axles , springs and tires .
Everything that went into the construction was the lightest possible .
So adding more substantial materials will take away from your carrying capacity and put you either closer to your GVWR or possibly even over weight .

JMHO: Not the RV you want to try towing around the country .

Thank you for your input Skip...the longer I work at it the shorter my adventure will be. I've remodeled one for selling and picked this one up for $600 to fix up to keep...never dreamed the plywood would've been stapled to metal joists and glued to styrofoam..lol

That’s a sandwich floor. 2 layers of 1/4” plywood with about 1 1/2” of styrofoam glued and bonded together.
I’ve repaired small areas before. If your floor is mostly gone, it may not be worth it to try to fix.
Depending on how much clearance your slides have, you might be able to put down 1/2” plywood over the existing floor. You will probably have to add joists underneath, also.

Thank you Kip. This one is only one layer of 1/4 inch and if it wasn't for all the wet rotton wood I'd just cover it like you said. The owners said the flush valve fitting on the toulet broke off while they had water hooked up to it siting at their house and didn't notice it till they were outside and saw water running out. Guess I will keep chopping at it...thank you for your insight..ill take any pointers I can get.
