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.
