The cold weather package in my Wildcat includes heater pads for the tanks. When overnight camping in cold weather, I found these pads are rarely needed because the furnace heats the tank area enough so the heating pad's internal thermostat kept them off. The colder it got, the more the furnace ran and the more the furnace kept the tanks warm.

The furnace draws a lot of power from the batteries so having 2 batteries for overnight camping in cold weather is important unless you run a generator. I found the tank heater pads didn't draw too much from the batteries once the furnace warmed things up.

I think this is well hashed, but my two cents: each device should ideally have its own fuse, if for no other reason than in keeping with the KISS principle. It is the right way to do it and might save time now, but cause headaches down the road.

True the 14g can handle 15amps, but just barely at 20 feet; but with both pump and heater on, the voltage will drop to around 10.6v or so, effectively causing you higher current than estimated. The pump, although small, does pull more amps upon start up.

Actual current on any device could be less that published, some alot less. Actual measurements should be in order.
