A normal RV furnace is a 12V (and propane) powered device. You should not see a 6A increase in the 120V power supply from using the furnace.
There are a few possibilities for what's going on. It may well be, as others have noted, simply that the EMS current display is not accurate. My PI EMS seems to have a roughly accurate current display, at least most of the time, but it's far from a precision instrument for current measurement.
Some RVs use heating systems other than a standard furnace, or in addition to the furnace. A heat pump could perhaps use 6A running. Some thermostats will also turn on the air conditioner fan to circulate air when the furnace is on, and 6A for that would be believable. There could also be an electric heater somewhere that's used in conjunction with the furnace.
