To get you going do you have a boost switch - a switch that connects the house and chassis batteries together, for use in such a situation.
You may have something turned on that you don't realize that drained the battery. In example, I have a switch on the dash that turns on a under-hood light. During the day you cannot see the light is on. If inadvertently left on it will drain the chassis battery.
Well. That would explain what that other switch on the dash is for!!
We have three toggles on the right side of the dash. The first one, we haven't identified, the second is for the reading lights on either side of the cab (kind of like map lights) and the third is for the generator. I know that first one was left in the 'on' position for a few days.
