Hi all, we have recently upgrade from a Jayco Eagle to a 2011 Jayco Expanda- loving it!! There are two power points under the dinette lounge one on the left has a cord plugged in running around to the left at the back of the sink the one on right has cord plugged in running to the back of the switches to the battery pack/pump and gas for HWS. Is the one on the left for running the hot water system on mains? Thank you.
