I also just purchased a Thor /Four Winds Motorhome. I also contacted Thor and here is what they told me! Thor purchased Four Winds in 2008 and did not get any info on the older motorhomes... We're stuck!
To help you with your problem when I'm hooked up to shore power I need to disconnect the battery using the switch above the door. So to keep the motor battery from going dead, I just turn it off. I have had numerous people tell me they have no idea of why it drains and isn't charged with the coach converter!
Now to my problem, I also need a build diagram as I want to install a Tornado black water cleaner on the back side of the tank! I looked and I think I know which one it is but don't want to start drilling!!
Need those manuals
