I happened to see this post and found it interesting. Since I am new to RV'ing, the very same thing happened to me. Trailer was in storage for about 3 weeks...went to the trailer and found absolutly no power to anything. The battery was dead. After talking to a Prime Time service rep, (Roger Stickel), he explained that the battery should be disconnected, or to install a battery disconnect. I charged the battery and everything was okay after that. Now, I do disconnect the battery and will have a disconnect installed. Wouldn't it make sense for a battery disconnect switch to be part of delivery of an RV? Is this standard practice with all RV's? If someone would have told me prior to delivery, I would have gladly paid to have one installed..
