All good just took a little swim other than it sucking up a shit load of water and had to be towed home. Took it to my buddies and pulled the plug and pumped the water out and drained oil/milk and cleaned the oil/water out of the air box. Still have a couple engine flushes to go before I call it good.
Thanks for sharing. You'll want to leave it in 4x4. You were right in thinking a blip of throttle would have prevented it from going over. In 4x4 the front wheels will pull you away from the steep slope. Let us know how many oil changes you end up doing.
