I just traded my 2000 X in on an 06 Xterra S (both 4x4). My 2k would go just about anywhere. I loved it!
I took the 06 up to Steamboat for the holiday. While exploring the town, I decided to turn around on a narrow road. I didn't realize how deep the snow was on the side and got stuck.
I put it in 4x4 and tried to get out. No good. I put it in 4x4lo and tried to get out. No good. The tires on the road just spun while the tires in the snow did little to nothing. The ABLS kicked in a couple of times - made that same annoying sound as when the ABS kicks in during a slide - kinda sorta made the truck rock a tad - and then stopped kicking in altogether.
Personally, I think this ABLS stuff is totally useless.
Here's me stuck:

I ended up getting pulled out by a Chevy.
I wish I had the lockers... still, I expected more. I honestly think my 2000 would have been able to get out just fine.
If this is the direction the xterra is going, I've just bought my last one.
