These are parts of learning your unit. Did the connection at the battery come loose on the way home? Check the connections. Look things over. Do you have a volt meter to check the battery directly? Do that. If you live close to the dealer, give them a call and talk to them. The battery should be no way 'dead'. Something that you did not openly see may have been left on. Can you plug in your unit at home to shore power. I am sure that you may not have a 30 amp plug at your house, so you should have/get a 30to15 adapter. Walmart sells these. If not able to plug into the house just yet, back your truck up to the unit and with the truck running, plug it into the cord (make dang sure that you unplug it when done and not rip it out of the connector,if you are not 'on the ball' and pull away) does the lights, etc. work now? Is the 'converter' switches on for 12v, look at the panel? Should be an easy fix if you take you time and walk through things.
