We purchased a 2002 Winnebago Brave from a private seller near Houston, TX and, unknown to us, it has a lot of electrical problems. We are fairly new to full time rving, a long way from home (upstate New York) and don't know who to trust as the repair shop that already did some work for us made the situation worse instead of better. Any help or suggestions would be greatly appreciated.
