Sealed undercarriage and water leak

[Dwhage24]

I had a water line leak in my bathroom and luckily it stayed mostly toward the back of my tt. I got everything inside dried quickly with fans and dehumidifier. But my question is underneath. It’s a sealed undercarriage and furnace heats my tanks. Was able to drain as much out as I could by just tilting the front end up and putting a small hole where it was sagging mostly. I let my furnace run mostly to get it dried out but I’m kind of worried that it’s not enough airflow to dry it completely out. Any thoughts or should I just keep running my furnace? I live in Washington State so it’s pretty wet here. 2016 Keystone Cougar and has the coroplast under it.

Can you not drop the coroplast to speed up drying? If it is attached with the self driven rivets replace then with self drilling screws when reinstalling.

Had a similar problem on a previous RV. I cut a 2'x2' square in the Coroplast at the lowest point. Pulled all the wet insulation out and let it drain and dry for a couple of days or longer. Replaced with new insulation, put the square 2x2 piece back in place and taped it up with Coroplast tape. You can buy the tape from Amazon (4" wide). When completed, it all looked new again. An easy chore, just time consuming.

Reference the rivets in newer RV's. Was told they were shot in like a nail gun. Extremely difficult to drill or remove. Best to cut and tape.

Actually they come out fairly easy with a hammer and pry bar.

^^^^Ahhhh, the old "wonder bar" as I call them. They are made in various sizes and I keep them all over the place. I'm always amazed at what I, and even DW, can tear up with one!!

The underbelly is held up with a combination of screws and power driven nails. The nails can be easy or hard to get out. I pulled my underbelly off and ended up using a combination of prybar, hammer, vice grips, and grinder to get them all out.
