Our first trip in our 2009 palomino thus past weekend. Successfully arrived, wentvto fill fresh water tank and the tank hadca seven inch crack in it. Nice that the dealer informed us of that. They will not make goidcon it either. Next, we arrived at site, unhitched, turned on lights and nothing! We had wiring checked, everything worked when it was plugged in at home, bought a new battery, battery Tender plus, keptvbattery on the Tender until day we left. We checked all fuses, battery also. Not sure if there is something on converter you need to press. Already made sure galley was suppressed enoiugh to trigger lights. Seems to be but there's also a hose coming out of the same area.frustrated, followed the lines to make sure everything was okay on roof part of camper. Can anyone help. This is awful pic but does someone know what it is?
