If you’re driving a rare semi-custom vehicle and it breaks down in rural Yoknapatawpha County, Mississippi, chances are that you’ll be dealing with the local mechanic as well as the RV place over the phone. Granted, you’ll probably be reimbursed in the end, but AFAIK most RV rental places don’t have national infrastructure, so you won’t end up with them sending out a wrecker, towing it to the local franchise, and handing you the keys to a replacement vehicle.
