My truck has the airbags installed with the in-cab compressor and activator switch and gauge located right near my center console. Now admittedly, this was installed by the previous owner of the truck (a friend of mine also,) so I don't know what he paid for it. But I can tell you that having the inflate/deflate control at your fingertips is worth whatever he paid for it. Having to get out, hook up a compressor, and check it with an air gauge just makes my head hurt thinking about it. Spring for the in cab. You'll be glad you did. Ride quality is improved, even empty--much less jarring spring rebound with a little air in the bags. And the ride with either trailer back there is smooth. Good luck!
