Air Compressor decision

Since this is in the truck camper forum I will assume space is at a premium. While I have no issues with the pancake type some have mentioned they do take up space and you do need 120v. On my previous truck and my current truck I have mounted a 12 volt Outback Extreme Aire Magnum air compressor and a 2.5 gallon tank. It has 100% duty cycle and can pump some air. On my previous as well as the current truck have it mounted under the bed right behind the cab on the pass side. It is mounted to the frame rail. I fabbed up some brackets that required no drilling of the frame. I then ran some hose to the front for my air horn and to the rear with a quick connect fitting. It sat under the previous truck for 15 years with no problems and the new truck for about a year. Only thing I have had to change is the air filter once. I have a coiled hose in the tool box that can reach all four tires as well as all my trailer tires. I use it for airing the tires back up from coming off road when required, airing up my fishing float tube, the occasional air mattress and any other reason one might need air.
