Sealing is a great idea, but only for prevention. Once swollen the doors will never return to their original thickness. After drying they may shrink a bit, but you won't notice. Most particle / flake boards, OSB, etc. do not do well around water. Plywood is more more stable and lighter
weight but more expensive and seldom chosen in the RV industry. Still sealing is a good idea for any wood product in the presence of spills, high humidity or liquid water. Sealing will be pretty effective on doors, probably not so much on floors. All sealers are permeable to water/water vapor, but they do slow down the process which is often enough. Best course is to avoid water.
