I have 5 gallons and two Viair 380's and it's good for raising it to drive and dropping it when I park but if I was in to playing with it a lot I'd probably go with like 12 gallons and 4 480's or something along those lines, that's a lot more money though. Also you have to decide if speed matters to you, obviously the bigger the air line the faster air will move through it, so you have to figure out if want want to run 3/8" line or 1/2" inch. you can also go really cheap with manual valves and 1/4" line, it will take like 5 - 8 seconds to raise it from all the way down to all the way up, but it will save you a lot of money.
