FR can authorize mobile rv repair services under warranty. Get them the best assessment you can, as stated, explain you CANNOT be relocated as a result of dealer scheduling. That is an undue burden.
If you cannot find the wiring issue easily, contact someone. Electrical issues should not be ignored. Where there is smoke, there is potentially fire. Faulty wiring is nothing to play with. Just say'n, express your urgency when talking to FR.
BTW, Denise Davis manages the CC Service Center. She is helpful and very cordial.
