Has anyone used this successfully on a Winnebago Boldt?

This can work on all maxxair/fantastic fan roof vents as long as the vent knob does not stick below the roofline. If the knob hangs lower than the flange (due to shallow mount of the vent), it will not work.

Can these be folded back partially to vent and cover most of the fan at the same time?

Yes, the first section of the vent (25%) can be folded down (and hangs) to allow the vent/light to come in as needed.

Will this help keep heat in during winter camping?

Yes, this will help insulate against the cold

Has anyone installed this on a Dometic Fan-Tastic fan?

If you read as in READ the description it clearly states in TITLE too that it does work same way for the Fantastic Fan. Note it states Fantastic Fan which is Dometic Fan TM branded. So yes it fits a Fantastic Fan that's the classic 14.5x14.5 size range. You install THE same way it discusses installing with the Maxxair fans. You'll need to remove the interior flange or finish cover and set cover down on solid flat counter or table surface. Then place the removed frame on top of the cover. Next take the supplied magnets and attach as they show being done. Now you need to secure these placed magnets with tape to keep them in place for good. Now return the frame or flange to the roof using the screws you took out and viola you can now put your magnetic secured cover up on your Roof Fan and have insulation and black out light curtain when needed.

Nice Looking and Very Functional MaxxAir Vent Covers

Installation was easy, and they block out light very nicely. They are easy to store thanks to the included pouch and their foldability. We are not yet sure if they provide sufficient insulation, but so far, so good. We recommend them.
