It is a fiver. The battery was fully charged when I left, hooked to a/c power when I got there and the battery is fully discharged now. All I did was charge it with my battery charger and checked for water.
So glad to hear I may have two problems!
Here is the thread on my a/c issue. I have had this camper since '07 and have been using a camper about 20 weeks a year for 20 years, always hooked to shore power, so I am an experienced camper, but basically have never had electrical issues.
