RV dealers are pretty bad at service anyway, so may I suggest you call a mobile RV tech. Even if it was a warranty item, which it sounds like it may not be, you can call LTV and get approval for repairs and be reimbursed. There is no need to wait months for some unresponsive dealer. Take your business elsewhere. If you Google around for mobile RV repair and read reviews carefully you may be able to find someone nearby to assist.
