As shown in last pic , both valves should be oriented in same direction ,either both horizontal or both vertical depending on normal operation or winterizing. (at least on every TT I owned or helped winterize.) If one is vert and one is horiz...you have it wrong...
It was a rainy few days at Algonquin Prov park...tarps kept us dry.
