I am thinking of heading the air suspension route.

I have a read a few threads on the topic and have one or two questions I'm still a little unclear about.

On the rear, it seems fairly simple - you just replace your current springs with an "air spring" and leave your current shocks in place (I have Konis from VC). Pretty simple and cheap it seems, and an air compressor isn't strictly necessary? i.e. you can just add a manual valve somewhere and get pumping?

The front is obviously different though, will you be relying purely on an airbag for taking car of the spring and suspension? Could you do a similar deal with a manual inflation valve?

Why did you start a new thread on this topic when there is one already in progress on this same page (as of 6/23/12)?

You asked about a compressor.. that was answered in the other thread.
No you do not need a compressor. Valving is also discussed.

Your second question.. doesn't ask for the peritinent info. The front is challenging because the shock is inside the coil spring in the OEM structure. You'd need to relocate the shock (custom fabrication).. or find someone who makes an airbag with a donut hole in it, (am not seeing how a donut hole is gonna work..)

airbags are made for cars with mc pherson style front suspension which has the shock running through the airbag. i dont know much more about them other than they do exist. alot of guys use them on rabbit/golf/jetta but you will need something meant to handle a bit more weight than they would use. google is your friend on this one.
hope this helps.

I suppose my question would be - why do you want the air bags on the front?

Usually when you're carrying a lot of weight it is over the rear axle. When using the system to level the van that can often be done by just adjusting the rear corners.

I'm not saying it is of no use, but seems to me you get most of the benefit from just having the air lift in the rear.

I would like to lower the whole van for things like my parking garage and highway cruising but would like to also be able to raise it for campgrounds and other scenarios where higher clearance is necessary.

check out air ride, they have a bag-over-shock design that you can use on the vanagon. not cheap, but probably the best way to go .
