I thought I would update you on our experience pulling the CMax over Memorial Day weekend. On the way out to Burlington (6 and a half hours) we followed the instructions and as several others experienced, we had a dead battery when we arrived. On the way home, we stopped at about 3 hours and started the car and let it run for 1-2 minutes. Then, continued on the rest of the way. Started fine when we got home. Any thoughts as to if that would be all it would take? A short stop every three hours? If so...we can handle that. Wondering though if we went multiple days in a row such as when we cross the country in 5 days or so. Would the cumulative effects of drawing it down make it not work in that case?
