 ===== roof vents in winter =====
 In winter you may want to run the vent on the lowest setting **pulling air into the camper**.  This will preserve your warm air at the roof, contribute to circulation of air, and help control [[hvac:dehumidifier|humidity]].
+===== power consumption =====

+===== installation =====
+Some vans have flat (or flat-adjacent) areas to facilitate mounting fans.
