Roof fans, ceiling registers, and the cover that is not a repair

RV 'vents' are four different holes. The roof vent moves air in and out of the coach. The ceiling register aims air-conditioner supply. The floor register is the furnace. The skylight is a window in the roof. A product for one of those holes does not fit the others, and the search results love to mix them.

Start with the hole. A 14-by-14 crank vent that died is a Maxxair conversation. A round ceiling grille blasting the dinette is a WKZO conversation. A 2-by-10 plastic floor vent that cracked under a shoe is QIPECO. A bright bunk under a dome, with no water stains, is a cover. Water stains are a roof job.

How to choose

• Dead roof fan, standard opening: MaxxFan Deluxe. Buy sealant separately. Don't run it as a substitute for an open window if you also need a cross-breeze path.
• Rude ceiling air, 4.5-inch cutout: WKZO. It will not close all the way. That is intentional.
• Broken floor furnace grille, 2 by 10: QIPECO. Pull the magnetic cover off when the furnace runs.
• Glare only: Lyrivan 16-by-16 cover on a 14-by-14 dome.
