Hi all, we hope to go out west sometime this year and I was wondering about the need of 4 wheel drive as a general need to pull off the road for a night or 2 while boondocking and maybe state and BLM lands. I know I won’t be able to pull up on the sand at beaches but not familiar with road conditions out west. We will have a Chevy 3500 express van with posi traction. Thanks, Glenn
