I have a 2012 crossroads sunset reserve 31BH the bathroom roof top vent for the fan assembly broke apart does anyone know the size of it or how to measure it properly for a replacement one it lifts with a crank in the middle.
The standard size is 14.5"x 14.5". I think there used to be different style hinges, I'm not sure if that is still the case. Look for the name of the vent and order the appropriate lid.
