While on shore-power, furnace works well on our 2006 Four Wheel Camper. On house battery system, insufficient power gets to furnace fan to run at necessary RPMs to activate furnace. In trying to diagnose issues have noted several symptoms: when on battery power, right side of camper (i.e. ceiling light on) electrical system shows "green" and battery good; however, when any electrical draw from the left side of the camper (i.e. ceiling light over kitchen is on), the electrical system shows "red" and charging of system required. This occurs even when the truck engine is on and charging the system. Have changed the battery twice and have kept it on shore-power trickle charge, yet problem continues.
We're looking for guidance as to next steps?!?!
