Well I finally got someone in customer service at Cruiser RV after a number of emails. They say their emails are down at the moment.
I asked if they have a schematic or drawing of my fuse panel in my 2006 X139 which I bought used. They said that they haven't made those for a while now and that back then no one kept good records so I was out of luck. Thanks anyway.
So are there any other forum members out there that own a 2007 X139 or any year close to that that could take a snapshot of their fuse panel and tell me what all the fuses are for?
Easiest way to figure it out is turn everything on, start pulling fuses/turning off breakers, and see what turns off. Had to do that with the fuse panel for my condo. Everything was labeled wrong!!!
