So I found another use for a decompression lever. Say a river you cross regularly decides to change as rivers have the habit of doing, and it gets deeper. Your intake may get a little water in it causing a hydro-lock condition. Just move the vehicle to shallower water, pull the lever and the hydro-lock condition is eliminated. A couple kicks and a few more and you're back to running.

Also, the back end of a lt230s will float with the tops of the tires (22x11s) still out of the water as long as no fat ass is sitting on it. With a little more flotation placed in some dead space in the front you should be able to float it across streams and such.
