unfortunately the water damage occurred while I was having emergency brain surgery in Florida in the middle of a pandemic, followed by 2 months of f radiation and chemo. While I was stuck in Florida the RV was home in Texas with the slide extended when a big storm apparently hit. The good news is the surgery and subsequent radiation and chemo turned out very well. But by the time I got home the floor was rotted out. I was thinking that if I had waterproofed the floor the damage wouldn't have been as bad.
I appreciate your comments about not sealing the floor. That makes sense.
I will tell you to be thankful for what you have. When you are a 20 year old you feel invincible. When you are 65 and one emergency surgery and a few hours away from death, you get a new appreciation for the things that are important.
