I'm looking to install some onboard air. My uses will amount to air tools and airing up 33's possibly 35's someday. Is a tank necessary for this application? My modification skills are pretty limited so I would be looking for as much of a bolt on kit as possible. My budget is about $500, but I would obviously like to do this as inexpensive as possible to meet my needs. What do you guys recommend for my 2012 Wrangler?
