As I understand it, they have both a new box and newer version on the new box. I recently obtained a version 1 boondocker box with a sled I recently purchased. I called Boondocker and they want $318 to upgrade to their new system, thats after I ship them my version 1 box and connector cables. They must be high. When the new price is $420, who would want to stay a customer with that kind of upgrade cost? Sad. I'm just gonna use it version one, I can still add a little fuel with it, which is good enough. If I was going to spend $318, I would spend more and get the new power commander that has the auto tune functionality.
