   Electricity is electricity. RV or otherwise it doesn't change. These   
   "technicians" at dealerships should have the necessary equipment to work   
   with. And even if they are low paid, even a democrat can be trained.   
      
   In the case of circuit boards, that is in my opinion in most cases, one   
   instance where just replacing the whole board makes sense. These things   
   are chump change to manufacture and on a pure cost basis, replacement is   
   a lot cheaper than trying to troubleshoot the issue, especially if it is   
   intermittent.
