I have seen the ARKPAK on BCF for sale, the black ones and they sell the 12 volt connection separately for $100. So I do not think it comes supplied with the unit. I am looking into one of these for my self as the whole portable side of things appeals to me and the fact that when you are not using it can sit there and maintain your battery is a good idea IMO.
But I am going to run a 12 volt outlet to my tub but also want to know do I need an isolator or something similar? I was thinking about just running some wires from the 12 volt adapter in the cab to the back so it will provide power when I have the ignition on or the engine is running.
Any opinions appreciated..
