this is typical in the RV industry. They do stuff different than anyone else. They determine the problem, inform manufacturer, wait for approval to repair, order parts, then repair. Any other service industry, does the repair as quickly as possible, files claim for reimbursement afterwards.
Maybe if the RV industry would raise it's standards and get some quality repair techs, they could operate under the same methods and make repairs go from months to days.
