Airing down, tallest tires possible and the most suspension travel possible so you can use momentum to get you through the tough spots, smart driving, rear locker, and aggressive tires on the drive wheels. I went with mud tires in the back and ATs in the front so I didn't have the road noise up front. I added a fast air compressor and Trailhead deflators set to 25 psi. I can air down further if I get stuck. I also carry traction boards and I have a winch on a front receiver hitch. I have a factory LSD but will probably go ARB someday if I upsize the tires and swap the ring and pinion. A lot of money for something that may not be worth it for me.
Compressor has since been hard mounted and hard wired. It's awesome! 25-60 psi all around in about 11 minutes.
She's one impressive beast
Running around in 6-8" of snow on FS roads didn't get me stuck so I went off trail, hit a snowman family and finally got stuck. First time I'd ever used the traction boards on my van.
