I see more going from juice to bags but I am going bags to juice.. just cant beat the sound of juice and ability to hit the switch whenever you want. hearing compressor(s) is annoying
I think you'll see a lot more bags to juice "conversions" on cars than you will trucks. Mostly because I believe it is easier to lay a car on juice than most air products available.
I see and hear about more people going from bags to juice. I've been hooked since I went to juice. Unfortunately my wife isn't ready for juice so I'm stuck with bags on my hardbody.
