I have always done both because building suspensions has not only been my job for 20 years but my life. I've done both extensively. I've installed air just as long as hydraulics. We would make our own air kits back in the day using air shocks, a compressor, and direct fill them. Then a company called air lift starting making a kit to level out trucks hauling a lot of weight. It was just a little compressor that would direct fill two air bags bolted over the leafs. We would take these kits and make brackets to lift our trucks still using the direct fill method with no tanks for reserve. As time went on I started getting more educated on the industrial apps. and started using electric valves off heavy injection molding machines. With these valves I could now start using a reserve tank and not wait for my compressors to fill up my bags. Most of you guys couldn't even imagine plumbing your compressor straight to your bag and adjusting your lift by turning the compressor on and lowering it by manually opening a ball valve that we mounted outside back then. We wouldn't go up and down while driving because it was strictly to get it off the ground to drive. You would have to get out and open your valves when you parked to set it down.
The main reason for this back then was the cost. I could do air ride for just a few hundred dollars as compared to over a thousand for juice. I only installed this air on customers vehicles as a cost alternative to hydraulics. I had a demo truck I almost never drove because it was embarrassing pulling up to the spot were everyone else had juice. Most of the minitruck guys were kids with very little money and it was this(air) or nothing. I started taking my little demo air minitruck to shows with me instead of my juiced Regal and a lot of people liked it and wanted it done. To be different not because it was better than juice. Well the hydraulic guys would pull up, clown the hell out of the air guys, laugh, and make fun. This created the anti-juice crowd.
I always have installed both and to be honest I like installing and working on air because their is no oil to clean up and I stay a lot cleaner. If you
