"AIR LIFT" air bag suspension enhancement install

I'm seriously considering doing a four corner airbag suspension. Mainly for leveling the van when we're parked - - including stealth camping.

It would also be nice to push it up to the top limit when going super slow over rough roads, or lower it down and soften it a little bit on a smooth freeway.

It'll be a lot of money but on the other we're still $100,000 to $150,000 below a used Mercedes based Outside Van.

The last message I got from the suspension manufacturer:

. . . Front struts are £3250:

Ducato, Jumper, Relay, Boxer X250, X290, X295 Front Strut Kit

Rear kit is £2250 but there is a 3 month wait for it:

Ducato, Boxer, Relay – Full Air Suspension Rear | AirRide . . .
In addition, I still would need to track down a controller, air tanks, and a compressor on this side. Not sure if I'll do it. However tonight we're camping outside of a ferry terminal and debating on whether to try to stealth with no blocks (heads down) or stick the blocks under the tires and sleep with our heads up. #firstworldproblems
 
@phil I'm talking about full air suspension (or this one). Sorry for the threadjack.

@subman719 I'm glad that you are happy with your air bag addition. I have considered doing that kind of an additional air bag. I thought if I did go that way, I would want to try removing the "overload" spring. My idea was that the van sits low by a couple of inches without the overload/helper spring, and I would make that up with more pressure in the airbag.

Since my primary goal was leveling, having the extra ability to "kneel" or "squat" was important. Now I'm leaning towards just doing full air suspension.
 
Please verify that having the two bags connected together with a T is safe.

My understanding is that if you get a little too much weight on one side of the van it will push air out of that low bag to the other high side which will make the tilt worse.

A bit like trying to balance on an exercise ball.

As I understand it, this can make the van very unstable on corners. Please check this and verify that having a T is safe before you continue.
