Is Fan Motor of Ventline # S0721-24-GC-F-1 RV Vent Hood Dual or Single Speed

Question:

I noticed on this fan that Ventlines PDF of the fan tells of a single speed motor page 14 see attached pdf file. Yet they have two different switches single speed vs two speed switch see page 15. Question I have for you is as follows: Do both switches and accompanying resistor come with the fan? Or does the van actually come as a two speed motor to begin with? Also how much is one of the vents that this attaches to for the exterior of the wall on my 5th wheel? Which would you recommend one with a flapper door on it or just one that is open all the time? I am living full time in this trailer so I am curious if there is a flapper door already in the vent or not. Or do they make an optional flapper in the hood vent so the exterior flapper would be unnecessary?

The Ventline # S0721-24GC-F-1 range hood features a single speed motor. The hood features two switches, one for the light and the other for the fan. I checked out Ventline's catalog, and didn't see that they had a dual speed fan available.

The hood doesn't have a damper, you'd need to use a # V2111-03 exterior wall vent that has a damper.
