jffnkrn and 4x4Dodger,
I apologize that your questions were not answered directly by Camping World. As far as the Rally's go they have been canceled for 2016. I am not sure at this time what the plans are for 2017. 4x4Dodger, our app does not have control of the battery life of your cell phone. Apps that utilize GPS tend to drain more battery than ones that do not. I would recommended buying an adapter so you can keep your phone charged while you are driving. I have also been made aware that you can buy an extra battery that attaches to your phone giving you at least two hours of extra battery time. I also just looked at your original post and it appears as if fellow members have also left some great suggestions as to how to save the battery on your phone. Enjoy the rest of your weekend!
