The flooding here in Nebraska is becoming a normal way of life. Today I drove my Chevy Express van into about 18 inches of water and the thing stalled out. Now when I try to start it all I get is a vibration sound like an almost dead battery.

So I figure it will dry out in a few days. I was able to call someone and got winched out and then made it home. But I am going to upgrade to a Tahoe or something similar with 4x4.

I have been offered a duce and a half but that is not practical for a daily driver. It would solve my high water over the road problem.

But.... If I get a Tahoe is there a package or a procedure to upgrade the electrical system so I can drive through water up to 24 inches? I am really wondering if someone can point me in the right direction on the web, not a full blown description of how to perform such an upgrade.

This is standing water, not flowing.
