Under floorboard holes

Hello,

I was at the Afton Mojave River crossing this weekend and the water is deep enough right now to go over the bottom side of the doors. I saw a few modified 4Runners cross and one got water inside along with a stuck Cherokee there as well. Knowing that I had open holes underneath my truck floor from taking my tube steps off, I was reluctant to go across and turned around.

Anyways, I would like to seal up everything underneath the floor in the event of future trips in the same area, and am wondering what else to do besides sealing the 10 tube step mount holes and doing the rear differential breather reroute?

Oh, and besides a snorkel, too.

 

Your rocker panel pinch welds have tons of drain holes, your doors also have drain holes on the bottoms. Water will get in really no matter what you do. If you really want to do some water crossings, pull the seats and console, then remove the carpet and padding. at least then when you get water in it wont make for a moldy carpet.
