Running lights and turn signals are from the trailer light module/system as are the brake lights. Assuming a powered trailer light module, those lights working means that you have power to the module.

It hints that your problem may be related to the brake light trigger signal. Are the RV brake lights working? Do you know whether you have an OEM (Mercedes) or aftermarket (powered module) trailer light system?
