Did I really have to unscrew everything off the floor?? No I get lazy about half way through and don’t bother to unscrew all of it but most of it. It is actually easier to deal with the floor with out the metal on it. However you could just leave it on and cut through it though. Over all this part of the process is pretty self explanatory if you have read up on converting a school bus to an rv or tiny home.
