After disconnecting the heating element in my fridge and putting a switch in the power circuit to the slide motors, my phantom draws have been eliminated.
Interesting. I have a later model 2015/2016 2604WS and the cutoff switch is out front under the propane tanks. In mine the cutoff switch turned off about everything but the Zamp solar connector and I think the emergency breakaway trailer brakes.
I can believe that the front slide could draw a parasitic power since it uses an electronic controller module. I updated the wiring in mine to eliminate the auxiliary inline fuses under the left front corner (one 30A for each slide) and move them to a power panel in the front storage compartment. This was part of my install of a solar controller and current measurement shunt.
I also installed a switch in my Dometic to turn off the door seal heater and eliminate that draw.
With a 100A solar panel was able to easily survive a 4 day dry camp outing in July. Warm days made the side awning very nice and cooling at night made A/C not necessary. So solar was a fantastic solution there.
