Viair is a known supplier and likely good quality. They have a wide range of onboard air systems. (Disclaimer - I don't have an onboard compressor, not an interest in Viair.) You could get by with a tiny compressor if you put in a storage tank to store high pressure air. As long as you didn't try to fill the air bags frequently (like every 10 minutes - not a real need to do that), a little compressor would do just fine. It would just run a bit longer to recharge the tank.
If you feel like you got good service out of your Firestone compressor than I would just replace it with the same one. On my last trip I had a bad air bag and used the crap out of mine. I had to fiull mine a lot because I was towing mu=y RV. I think mine is taking longer to fill my air bags then before. I am looking at replacing mine after winter. I will just get the Firestone one. I would like a bigger compressor though.
My compressor is extremely slow to fill and bleeds off over night, never bleed off before. Id like a bigger compressor as well. But don't know which one to buy. Im looking at Firestone WR17609377 as my replacement
I’ve been running the Air Lift 72000 Compressor for over two years now on my 2011 F350. So far it’s given me no issues. I installed it on the frame just above the spare tire and ran the power wiring to the fuse box under the hood. Works great.
EDIT: I guess the 72000 has been phased out and replaced with the 74000 and 74000EZ. See the link below.
Easily install your WirelessONE compressor with this 25980EZ wireless compressor kit from Air Lift. This kit comes complete with the ability to hook up to an iOs or Android app. It also includes a mounting kit to secure your compressor under your vehicle, to the frame.
You should really look into the wirelessly controlled 74000 if the switch doesn’t work. It has a manifold that controls each bag together or individually. I’ve never lost air on a drive or sitting overnight. And it only takes about a minute and a half to get my bags to 85 psi.
