The "dc" option as far as I know was really intended for motorhomes to use while traveling and being supplied by the alternator. As you discovered, the battery in a trailer won't last long and the umbilical won't really "top" off a battery in a trailer. Your best bet is to drop a hundred bucks on a new battery, switch to LED lights and stay away from the DC position. You can shut it down for short trips without the food spoiling. Not sure if you can run the fridge on propane while the trailer is folded up, but someone else on here can advise about that I'm sure.
