I found out the hard way that the little batt,'s don't have much reserve capacity. Parked for a while and left the defroster/blower going (it was cold and raining out) for 15 min.'s or so while I had a conversation, and then NO START. According to Rob our blowers draw 30 amps or so, I guess depending on the fan speed; and I may have had the rear defroster on but I don't think so. Anyway, I won't do that again. He also said he was looking into the Spec.'s and told me I would have done better if I would have left the lights on rather than the blower (as far as running the batt. down), and in hindsight I know I should have started it up after 5 or 10 to be safe (or kept it running). Walking in the rain for help was something I haven't done in many,many a year. 32 Krazy, sorry to get off track. Hope you figure out how to get that dual to fit.
