DPDT Switch for Battery Bank
I have a WFCO Converter (110 to 12) and a power panel (12V and 110v) with my travel trailer. One side is fed 110 v and the 12V panel is fed from the single 12V battery on the trailer tonque. I am in...

So the -ve side of both battery banks (2X6V) and (12V) should be trailer grounded? ???? losses this way. Then switch only the +ve to the 12V power panel. Doesn't matter about the 110 to 12 converter from shore power when boondocking! Already have the off/1/2 switch. Should any protection be put in the grounded lines? Thanks again.
Yes grounded to the trailer frame as a floating ground system like a car. This does not mean you have to use the frame as the primary wiring for the - side. Just that the - of each battery should be bonded to ground on the trailer at some point.
Remember that when you are plugged in, the frame connects to earth ground via the 120 v system, and often the water in the plumbing also connects the frame to earth ground. So use the frame also as the ground reference in a sometimes floating 12v install.
