As many here have said there is no easy definite answer to how much you can air down. There are just too many factors. Even so, being in the teens with your truck at low speed should be fine. Youll be able to go lower in an emergency, just raise the tire back up to a higher pressure when clear of the sand or snow that you couldn't pass through.
In terms of PINS you should be able to clear most of that island without having to use 20 mph momentum. With the right air pressure and four-wheel drive you should float through nicely.
