I have a 2008 Lance 1055. In mine the wires came down from the roof and went into an area under the sink where there was a splice for a controller then it went to the battery compartment. other lances of that era had the wires behind a cabinet panel. in any case it was a straight run down from the roof then over to the battery. I put 200W of panels on the roof and used the Lance 2 pin plug that had 10g wiring. I pit the charge controller and a cut off switch on the side of the cabinet next to the step up to the cabover then used the prewire over to the battery. Whole set up including attaching the panels took less than two hours. It has worked fine for many years now.
