briansue, the stuff you have is light-years better protection level than what most RVers show up with. A biggie is to blow out the microwave control board, that is probably the number one complaint I see. I don't work on them. Cities have dedicated businesses that repair everything from appliances to refrigerators to hand drills, all with factory parts. Cost is very reasonable. Converter control circuitry is another PITA and I am unaware of anyone down here even in Mexico DF that repairs RV converters.
Many of these problems could have been avoided. I probably mentioned it on this forum but in the 1980's I was parked 100' from a large 5th wheel. I heard yelling, and looked outside to see a dozen people at the rig or running toward it. A woman had gotten electrocuted off a hot skin. I continued my journey a few hours later - I must confess it shook me up.
