Trimark door latch striker (made of cheap potmetal) broke while refueling. As the vehicle only has one door this tapping occupants inside rv until tools could be located and the door disassembled from the inside.
Windshield wiper toggled - right wiper gets stuck under left arm - making wipers stop until physically released- not very good stopping on interstate 80 in the rain
