How is the responsibility for the breakdown determined? Updated May 27, 2022 15:39 Depending on the situation, it may be unclear what exactly caused the breakdown. If it is not clear whether a mechanical issue caused it, wear and tear, or another reason, the repair shop where the RV was towed will need to inspect the RV and determine the cause of the breakdown. The shop will be able to assess what happened and provide an explanation and cause for the breakdown. The party responsible for the breakdown will also be responsible for the cost of repairs.
