And though not always possible, the MH should be parked with the reefer side in the shade as much as possible.
Something I'm going to try is a large piece of the reflective bubble wrap. Maybe one of the large pieces for MH windshields. Then take two of the rubber suction cups with hooks on them to hang the insulated bubble wrap on the outside of refer. The hooks would hold it away from the refer back to provide shade to the refer and allow air to flow through the refer vent. It can't hurt, we'll see if actually helps.
