Com'on guys... Did no one learn from my mistakes...
When Hummer says 24" water depth they mean it. add an inch for the 37s...
If the water comes in, which it will, it shorts out everything. One of the main processors is on the floor under the passenger seat.
I know. I had water up to the seat cushion on the passenger side of my previous Hummer, an H3, and it shorted out everything to the point where my insurance company totalled it.
Also, just for your info, if you are going to do this again:
1. hit the hill with some momentum
2. hit it a little to the left or right, then steer across it. You won't be in the holes that way.
3. Make sure you are locked and in low 4.
4. You forgot to cover the jeep with mud as you went by.
5. Why are you slumming with jeeps, anyway?
6. Don't publish your failures, only your successes. I want to see you make that hill, not puss out!
Anyway, be careful. A dead Hummer is a terrible thing....
