Query: Viair onboard air kit 20052

Complete waste of money. You would be far better off purchasing the components separately and making your own system. You end up needing different electrical connectors, plus the tubing that comes with the system is almost unusable. It's impossible to straighten, and cracks in extreme cold. A rubber hose with your own fittings would be far better suited for running the hose to your tank. However, you still need to use some of the small tubing if you plan on using the Viair gauge/switch.Overall, I'm really disappointed with this. For 100 bucks including shipping, I would expect more. I ended up spending about 50 dollars more just to make this adequate for what I needed. I will say, however, that the Viair gauge/switch is pretty decent quality and looks great once installed.
