A PLAN B is using the truck jumper cables when you 12VDC with alot of current.
Using the truck to trailer cable will probably only give you around 6 AMPS or so of DC Current.
I have nosed my truck up to the 5th wheel battery a few time to jumper it to get my slides in and out.
You really should be using the pedestal power to do if it is available but sometimes you get caught with just the trailer battery and you have found out it went dead on you before you got the job done.
The next time you hook up to shore power you need to determine if the system is charging your trailer battery right away. Something went belly up on you here as your battery should have been charged up ok after being connected to shore power for that long of time. Everytime we hookup I use my mulitmeter to see if the battery voltage jumps up to 13.6VDC or more. This is your life blood so always take good care of your batteries.
We poor campers just can't go out a buy another battery every other day... My batteries were installed in 2008 and still going...
