This simple, hand-operated roof vent lets musty air, smoke, heat, and cooking odors escape your RV or enclosed trailer; and it lets fresh air in. There's no need to connect wires or operate any controls. Just turn the crank for instant ventilation and sunlight. The opaque white dome keeps light out when you crank it closed. And a removable, easy-to-clean mesh screen keeps bugs, leaves, and other debris from entering your trailer through the vent.


This vent requires a 14-1/4" x 14-1/4" opening in your trailer's roof and ceiling. To replace an old vent, install this vent into the existing opening. If your roof does not already have a vent, you will need to mark and cut an opening between roof joists to install this unit.

Video Transcript for Fantastic Vent RV Vents and Fans - Roof Vent - FV800800 Review

Today we're going to be taking a look at part number FV800800. This is the Fantastic Vent RV or trailer roof vent. The roof vent is going to let your hot air out and it's going to bring cool air in, that way you can circulate in your RV, camper, and closed trailer. This unit is going to allow the air to circulate while your RV remains locked. It's going to feature a bug screen right inside here. That can easily be detached for easy cleaning. This is a hand operated unit, so it's going to make it very easy to open and close the vent from inside your RV.

There's no need for electrical wiring. If I flip it right here you can see that hand knob, on this side. That's going to allow the vent to open and close. Nice, easy design. This is a white polyethylene dome.

That's going to block the sunlight when it's closed. The interior trim piece . These two pieces just simply detach. The white interior trip piece is this piece right here. It's made from a polypropylene material. This is included.

It's got a nice design right here on the base. This is going to be the part that you would see from inside your RV, camper or trailer. See it's got the nice lip there and the mounting inaudible 00:01:19 that goes around the perimeter of the trip piece. Very simple installation though. All the hardware that you need is included. I'm going to set the interior trim pieces aside and we can focus on this piece right here.

I'll go ahead and operate that hand knob that way you can see how it easily opens and closes. This is how far it's going to open and then when it's fully closed . It's really going to do a good job at blocking the sunlight from coming into your camper, RV or trailer. The product is made in the USA. It is designed for RVs, campers, and trailer roofs that are up to four inches in thickness. The rough opening size that you'll need in your roof and ceiling is going to fourteen and a quarter by fourteen and a quarter. These two pieces simply just slide together. Just like that. You've got your mounting holes that go around the entire perimeter of the piece that would be on the roof. Then you're going to have four mount locations, one on each corner on that interior trip piece. I want to go over some measurements real quick with you. If we take a measurement of the actual width, the portion that would go inside the roof. That's going to give us a measurement of about thirteen and three quarters of an inch. The mounting holes . This is a square design so that's going to be thirteen and three quarters by thirteen and three quarters. The mount holes for the interior piece, that's going to be separated on center, those holes, by fifteen and one sixteenth of an inch. Again there are going to be four of those, one on each corner. If we measure outside edge to outside edge it's going to give us an overall width measurement of sixteen and one quarter of an inch. Again, square design so sixteen and one quarter by sixteen and one quarter. When this is mounted the vent is going to extend above the roof when it's fully closed by about four and a half inches and when it's fully open that's going to increase to about eleven and a half inches. Again you're going to get all the mounting hardware that you need for a complete installation and you're doing to get a nice detailed set of instructions and operating instructions. These are going to walk you through the installation process, step by step. It's going to allow you to know the different things that you need to do as the owner. Maintenance, cleaning and all that stuff. Installation instructions and owner's manual. It's all included. That's going to do it for today's review of part number FV800800. This is the Fantastic Vent RV or trailer roof vent.

After a year this thing looks like it's about to break. The top doesn't sit straight anymore so there isn't a tight seal. Generally just a cheap product that could've been done better. 714089

The website was very helpful in providing the information that I needed to make a purchase decision including a video. It was by far the best website that I visited and I could see that these guys were doing things professionally. Vent was shipped within hours of my order giving me more confidence on my choice. The vent is exactly what I ordered and I am very pleased. Great website, great service, great price! 319037

Great Product, Easy Install. I replaced a leaking A/C unit with this vent on my pop-up trailer and it works great. No more leaks and it allows for some venting of hot air. This is the basic, no fan, model but it's easily upgradeable to a motorized fan if desired. 219662

  • Fan-Tastic Replacement Trailer Roof Vent Recommendation When Base is Damaged
    If the base of the roof vent is damaged you'd have to replace the entire thing as that's not a part we can get unfortunately. The Fan-Tastic Vent RV or Trailer Roof Vent # FV800800 that you referenced would be an excellent replacement.

  • Do Powered and Non-Powered Trailer/RV Fantastic Roof Vents Fit the Same Size Opening
    Fan-Tastic Vent RV or Trailer Roof Vent # FV800800 fits in a 14-1/4" x 14-1/4" rough opening size. If that is the size of the hole you cut then you are good to go. Models with the electric fan, such as # FV801200, fit the same size opening. I recommend just using the model with the fan because even if there isn't power running to it yet you can still have the lid open to vent hot air.

  • What to Use So Vent Can Remain Open on Horse Trailer
    In regards to a vent for a horse trailer, there is a way to keep them open with a vent cover.

This will allow you to install the Fan-Tastic Vent RV or Trailer Roof Vent # FV800800 which you can then leave open if you use the Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Cover # FVU1500GR (Smoke) or # FVU1500WH (White).

  • Troubleshooting Fan-Tastic Vent Fan That Seems To Be Losing Power
    It really sounds like the motor for the Fan-Tastic Vent Fan in your Chinook RV is at the end of its lifespan. Before replacing it though I recommend just making sure the power wire to the fan is still in good shape and securely connected. It's possible that the slower speed and sporadic operation is just due to a lack of power actually getting to the fan assembly. If all of this looks good though the motor is likely the issue. We do have the Replacement Fan Motor # FVK8017-00, which...
