Mine should be pretty similar to yours Viar 100% duty compressor, 2.5 gal or so tank mounted under the bed. Mini oba install on my new tacoma discussion in ' 2nd gen If you have oba and an air tank you don't need to leave as much air space in the water tank, just an air line with an air pressure regulator set to. Can someone clarify how much oil i should have put in my truck at the last oil change I'm using 5w30 (not that it affects capacity)
