1992 Dodge House Battery system questions

[Digger Dawg]

My 1992 Dodge doesn't have the battery disconnect toggle switch on the monitor panel so, does anyone know where I can find it or even if this model actually has one? Also, I found the battery underneath the seat behind the driver and it appears to be a regular car battery. It is on a metal shelf open to the elements by the "shore power" cable. It appears to have enough room to put two 6V batteries that I am thinking of upgrading to but still need to find the disconnect switch or recommendations on what to install.

Also, I don't have any roadtrek manuals for this but was able to pick-up a nice set of factory Chrysler/Dodge Mechanic manuals for it. Are there any aftermarket manuals with decent electrical drawings for this model out there?

OK, the best that I can gather is that my system is what I would call a Roadtrek Gen-1. It uses a MagneTek 32 Amp Power Converter with Battery Charger, Series 6300A Model #6332 with Options: CNIBA and a Date Code of 522. Instead of a On/Off Switch on the Monitor Panel it uses an isolator under the hood though I've yet to figure out exactly what it looks like and where it is located as there seems to have been a few "modifications" performed on the old girl in these past 32 years. I'm more of a visual person so if someone could point me in the direction of some descent photos of an original set-up, I would be greatly in their debt.
