The one going down goes to Bat #1; The one going left goes to battery #2. The remaining two wires are connected to the "common" One exits the top going to my Inverter (via a 150 Amp fuse) and one exits to the right going to the coach converter.

You are correct that electrons depart the negative terminal and travel via the circuitry to the Positive terminal. That is why the negative terminal is "negative"... It is loaded with negatively charged electrons that were stripped from the positively (now) charged plates. Without the negatively charged electrons the atoms of the plate become positively charged due to the Protons in the nucleus.

I still break the positive with my switch. In the "big scheme of things" it really does not matter what you switch as long as you do not complete the circuit. Most folks follow the convention of breaking the red wire used in negatively grounded vehicles like our campers.

If you switch the positive at the battery you will never have the posibility of a short inside your trailer.

My 2 cents
Iggy, this is not the case. The electron content of the battery will not change if you get a wire and go from the positive terminal to the dirt (or frame). There is no way to get more electrons into the battery than there are protons in the battery. Electrons have to leave before new ones can come in. Thus no way to short the battery without a connection to the negative terminal.

Their is many reasons to switch the negitive wire in a circuit but I'm not going to get into that.
Can you answer this question.

Why do builders place a fuse on the positive wire closest to the power source?

The answer will tell you why you need to switch the Positive wire and not the Negitive.

Where do you get this switch and do you install it outside on the frame next to the battery or does it have to be inside somewhere under cover?

Usually put in the compartment near the battery. This makes it easy to disconnect the battery after you have disconnected and parked for storage.

I put mine in the toe kick area right next to my power center.
Since my battery positive lead ran uninterrupted from the tongue to
the power center this made adding a cut off switch easy and I didn't even
need any extra wire. I just cut the positive lead and connected both ends
to either side of the switch. I'm just using a single battery switch.

Go to amazon.com and look for battery switch or harborfreight.com
or go into an Autozone and ask for a battery disconnect switch.

Many of us use this one. It's a little pricey but probably the best.

I see this one used often as well, mounted right on the top, or side, of the battery box...
