I put our unit in storage for a month and came back to a dead battery...ok fine...I thought I would connect the truck (F250 PSD) to the trailer and then after a few minutes I could operate the leveling system to reconnect the trailer. But after 10 minutes I still had no power to the inside of the trailer (e.g. 12V lights in kitchen), and the leveler didn't show any voltage (wouldn't even turn on). The trailer was connected with power as the exterior trailer lights went on once I connected to the running truck.

I ended up running a long electrical cord to a 110V outlet and then the trailer came to life and I was able to lower the gear and reconnect.

Here's the question-how long should I have to wait for the tow vehicle to charge the dead battery before I can use the leveler? I will be storing the system often and can't always depend on a 110V outlet nearby.

I have thought about removing the trailer battery and taking it with me so that I can bring back a fully charged battery.

Any other options?
