Lots of luck getting anything useful. I contacted Dutchman about my 2012 Komfort soon after purchase. I got a rough drawing of the plumbing and a floorplan showing all the electrical outlets with voltage and current specs. But no specific wire runs or water runs. IMHO, I think the installers make up the runs as they go. I found a DC wire run that had parallel 10 fuses. Obviously that's not 20 amp protection.
