I do not think the air suspension is on all 4 wheels but just the rear, like air bags but with a pump that operates automatically. I had a system in a cadillac, you put something heavy in the trunk and it pumps it way back to level.

Actually I stand corrected, the schematic shows all 4 wheel adjustable either up or down but not independent front/back

Thats what made me wonder. If all four air bags operate at the same time what happens when the hook up that heavy trailer in the article. I wondered if a computer chip auto levels the back end. I thought I read about an auto level feature but can't remember.

I'd strongly suggest you check out Consumer Reports reliability and frequency of repair ratings for the Cherokee before going for one. I'm a subscriber -- it's not a pretty picture.

Possibly when you pump in more in the rear it will rise to a preset level and then there is a bypass/relief to bleed off any excess. similarly in the front, if it does not need air, it may bleed off.

Plus another 25% for fuel and at least 50% for oil changes!!

Any reasonable factory-integrated air suspension system will adjust as required to reach a level ride attitude. Normal systems with air at both front and rear will adjust front and rear separately to reach level, and may add manual control of height, as Quadra-Lift appears to do in the control panel image shown by Jim's link.

It would be strange for a factory system to provide any way to deliberately set the ride attitude nose-up or nose-down.

In town right now, gas is $1.05/liter and diesel is $1,10, so that is less than 5%. I have seen near 15%, but that is not common. I know it is likely different other places, I just looked at the Calgary costs.

Diesel engines last a lot longer too. Fuel economy, at least in full sized pickups is a bit better too.

For me, the promise of the better performance power wise, without having to go to a larger vehicle is what I like best, even if it costs a bit more with all factors figured in. If other manufacturers would offer a good diesel in their mid-sized SUV's, I would be looking strong at that too. This competition would also bring the costs down too.

My wife had a 02 Jeep Grand Cherokee Overland and just recently traded it in on a new 4runner. Although she really misses the creature comforts and the V8 of the Jeep, I really don't think you could give her another one. For the most part it was a decent vehicle, but once it started to get close to the 200k mark the mechanical issues were numerous. Obviously this is a sample size of one, but when you searched some of the issues, she wasn't alone. As mentioned above, you might want to check into the consumer reports.

While thought of a diesel is pretty nice, the added maintenance does add a bit to the cost of running the vehicle. If, and this is a big IF, the engine does have any failures or issues, the cost for "diesel" parts are crazy. Injectors can easily run into the thousands. Having said that, good maintenance and a decently built engine should run for years.

Gotta say I love the look and feel of the new Cherokees.
