Air Over Leaf - minimum requirements?

[Gary]

I put lowering leaf springs on my 72, and I'd like to improve the ride and raise the rear end up just a little bit (1/2 to 3/4 inch at most), is there any reason I couldn't just get the Air Over Leaf, and install it and put a simple tirevalve, maybe in the bed of the truck or someplace easy to get to, to pump the bags up or let air out as I need? I'm simply wanting to "set it and forget it" I don't have any desire to raise and lower the ride other than perhaps add a bit of air if I'm gonna haul something heavy from time to time.

So for a minimalist setup could I simply get the system http://www.ridetech.com/productinfo/airoverleaf.asp seen here (probably the 2000 lb system would be PLENTY) and just add air manually when I need it?

Any reason NOT to tie the bags together and fill both at once?
