The snorkel worked well.
Going fast through the water was a little too much stress on the front lip though and it departed. Someone was kind enough to wade in and grab it for me, but it's not going back on the car.
The front bumper works as-is. I'll take a look through my scrap collection in the week ahead and figure out a better design for a dual purpose 'bow-splitter'.
It was very rough terrain. The Xbox did great and I don't think anything broke, just a few new dents and scrapes.
