Battery disconnect wiring
On the house batteries, do you break the positive or negative on the disconnect. Am seeing it done both ways?

Break the positive as close to the battery as you can. This keeps the positive from grounding out further down the line and causing a short to ground.
That's my opinion too.
On the other hand, if the negative connecting to the chassis ground is broken, then shorting the positive line to ground doesn't cause any difficulties either (well, assuming there are no voltage sources on the "other side" of the system like the converter, which applies in either case). No current flows because the negative lead is disconnected and you have no circuit.
Admittedly, I guess I do prefer switching the positive side, but not for any really solid reason other than it, well, feels like the proper way to do things. It's like washing dishes in the left side of the sink and rinsing them in the right side, which just seems to me like the proper direction to do things in, for no really scientifically justifiable reason.
