How is the responsibility for the breakdown determined? Updated December 10, 2021 19:39 Depending on the situation, it may be unclear what exactly caused the breakdown. In this case, if it is not clear whether it was caused by a mechanical issue, wear and tear, or another reason, the repair show where the RV is towed to 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 as well as a cause for the breakdown. The party responsible for the breakdown will also be responsible for the cost of repairs.
