What should I do for a Florida Build.

1..........Push button inflatable pontoons on each side (under the running boards).... Keep her outta the water.....!!
2..........Very long shaft outboard motor clamped to the Tail Gate...

In 24" of water, you would be driving past all those Ridgelines with the "uni-body" design that are just floating toward the ocean.... If the H2O gets to the point you are starting to float....deploy the pontoons and start the outboard...

 

It's for when your rear dif gets submerged in water. It allows the diff to let air out without letting water in through an a.c. tube that is routed up higher into your gas cap or rear tail light. It should be in the sticky threads section.
