With the coach running, and things like OTR on, does you battery balance light come on? Do any of the battieries look swollen? Have you driven the coach, to see if the smell goes away or subsides, and then upon stopping at a light, the smell returns?? We had this happen in our H3-45 right after Katrina hit Mississippi. Luckily, there was an Interstate battery shop open near the Jackson Mississippi Airport so we bought 4 new chassis batteries. One was toast, another was swollen, and the other two seemed OK.
