I ended up replacing my DC voltmeter with a different one which has shunt that I located in the battery box. Now I can see amps and watts being drawn from the battery.

The first picture is the old meter. I just removed it and made the cutout bigger for the new one. The wires for the shunt run through the back of the upper cabinets and then down through the back of the sink cabinet and out into the underbelly through the hole where the water lines come up. Then just ran them up to the batteries.
I still have to clean up around the faceplate where I cut the hole. And I'll get two new 6 volt batteries in the spring to replace the one cheap 12 volt battery that they put in. Right now it's all closed up for the winter.
