I figured the compressor seized up and limped to a gas station to air up. When I got back to camp I crawled under and found the breaker tripped for the compressor. I reset the breaker and tried the compressor again and it started up but within a minute or so the same thing happened. Sounds like a bad compressor to me and the bummer is I won't be able to air down anymore on this trip.

Not expedition ready is what you're saying.

Curious if you noticed your rear tires spinning? both of them?

30 psi should be fine off road, and I agree the sway bar disconnected.

I have noticed rear limited slip may slip more than desired or need slight braking.

The observer, the wife, who was standing on only one side, said she saw both front and rear spinning. I'm getting the locker and of course will disconnect the sway bar next time. Thanks to all for the input.

I have found that a front locker makes a huge difference in a heavy van. I'm not saying a rear locker isn't a good idea, but by having a selectable front locker has pulled me up small hills where standard 4-wheel drive has failed me. I do have a limited slip rear. The main problem with a front locker (even selectable) is it can run you off a cliff provided you're not careful. You just have to be aware what can happen...sometimes you just can't get it to disengage quick enough.

Interesting...
Out of curiousity where is said hill?
Here locally in San Diego or elsewhere?

BTW... I enjoyed the blog, as did our dog.

The little hill that I could not get by is in Capitol Reef National Park, Utah. Last night we spent the night in White River National Forest in Colorado. On the way back I went up a little hill that that was very similar to the one I could not get by in Utah. There will be video posted on my dog's blog later tonight.

The van went up no problem. It worked just like it should have in Utah. The tires were not even deflated this time but the sway bar was released. I am starting to think that "Woodbee" was right about the rear not properly engaged. Even though my wife said the rear was spinning, she may have meant the wheel was turning - of course not the same thing.

Anyway, I am very please with the way the van just motored up the rutted and potholed trail I went on yesterday and today.

I think you found your problem. The only time I ever had to winch my self out of a "temporary delay situation" was because the green 4x4 light was on but I was not engaged. I am always amazed how far this behemoth vehicle gets up 4x4 trails using just 2wd.

4wd with open differentials is really still only 2wd....

Reducing sway stiffness (by disconnecting) will really help when running an ope diff, or even limited slip.

and 2wd is really 1 wheel drive. Makes you wonder how motorcycles go

I seem to remember somebody else on the board having the same problem
