I think that the principal place you can get into trouble is the chassis wiring, because both the coach and chassis manufacturers get involved with it. This single issue gave us many hours of issues with our new home over the first several months. To make matters worse, the nearest Workhouse facility is almost a hundred miles, so things got testy on an occasion or two. If the issue is clear, no problem, but if it's a gray area, you feel almost like you're in that wonderful limbo between Microsoft and Dell, if you get my drift.
