Wow to Thurman. Lot of work if you have the time and ability. Not adding much to the discussion in my case...I have the 2004 GS-260, but it does have the 4" square tube back bumper and spare tire (which doesn't seem to hold newer/better sewer line connectors/caps). I've been taking the cover on and off to connect/disconnect a small solar collecor when parked in outdoor storage, but I think I'm missing a shut off somewhere in my process, because my battery seems to drain quickly instead of supporting the electric tongue crank, slide motor etc... Do I need to turn off a breaker in the panel under the rear-located stove?
