I added a coat hanger rod to my Sunset trail . The swivel TV still turns . The screws go into a 2x4 that is on either side of the vent trim . Just used the same holes in the trim cover . And the chrome end bolts are only in the rod , not into the ceiling .
It was a rainy few days at Algonquin Prov park...tarps kept us dry.
