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 smoke-colored dome filters UV rays while still allowing light in when 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 - FV800900 Review

Today we're going to be taking a look at part number FV800900. This is the Fantastic Vent RV or trailer roof vent. The roof vent is going to let all that hot air out and it's going to bring that cool air in that way it can circulate and bring fresh air into your RV, camper or enclosed trailer. It's going to feature a hand operated knob. See that right here Nice design so you can get a nice grip on it when you're ready to operate it. That's going to control the up and down movement of the dome.

It's really easy to open up all the way. Right there is going to be all the way open and really to close. Now before I close it I just want to show that in here is going to be a built in screen. That can be popped out. That's just designed to keep out insects but it easily detaches that way we can clean that when needed. Now when closing you're going to notice that there's a nice sealer that goes around the opening so as you tighten it down, it's going to create a nice tight seal so it keeps out all those unwanted items, especially moisture.

It's going to feature the smoke colored polyethylene dome. This is designed to filter those UV rays but sill allowing light in. This is a two piece design. This piece right here is going to be our interior trim piece. This is made from a polypropylene material. It's got the nice garnish right here.

This is what we're going to be able to see from inside our camper, RV or enclosed trailer. Nice design, bright white color so it's going to match most of the interiors out there. It's going to feature four mounting holes, there's one on each corner so you don't have to worry about having a ton of screws visible. There's just four mounting locations. This is a nice piece. This is included.

The unit overall is a very simple installation. All the necessary hardware that you need for your full installation is included. The product is going to be fully made in the USA. Again, these two pieces just snap down, fit into each other. Now when installing this the rough opening size that's needed in your roof or ceiling is going to be about fourteen and one quarter of an inch by fourteen and one quarter of an inch. Now if we take an actual measurement of the width of this piece here, it's a square design but we can measure this and that's going to tell us kind of the exact opening that we need. So measuring from this point here to this point here, it's going to be about thirteen and three quarters of an inch. The overall width measuring from the outer most point of the flange to the same point on the other side, that's going to give us a measurement of about sixteen and one quarter of an inch. Now the mount holes on that interior piece, those are going to be separated on center by fifteen and one sixteenth of an inch. You're going to have your four mounting screws for the interior piece and then you're going to have a whole bunch of other screws that are going to be used to mount this top piece into the roof. Now when the vent is fully installed in the closed position, it's going to extend above the roof about four and a half inches when closed. When open that's going to increase by about eleven and a half inches. Now when you're ready to replace your old vent and install this one, you simply just install this vent into the existing opening. If your roof does not already have a vent, you'll need to mark out and cut an opening between the roof joists in order to get this vent installed. That's going to do it for our review of part number FV800900. This is the Fantastic Vent RV or trailer roof vent.

This is a great alternative for those that have a functioning Fantastic Fan but the plastic parts are degraded. For less than half the cost of a new Fantastic Fan assy you can pull your fan and transfer it over to this new housing. Some effort is required to cut in a new rocker switch hole and of course you have to trim the inner trim bezel to match the depth of your roof but that has to be done with any new vent install. 318734

Will let you know later if it is working ok and not having any problems 622040

Finding a skylight over your bed in a camper van is a challenge when the only size available is dictated by the space between the braces. Here, our van only accommodates a small 14"x14" cutout. I thought of the Dometic Heki Micro but that is not available in this country - and the cutout is 14.25" anyway. So, this is the only serious option I could ever consider. All other products I evaluated were so flimsy that I knew their reliability would be an issue. I wanted to install this once and not have to replace it in a few years as I assume many of you also desire. Our 2018 Ford Transit-250 mid-height roof is curved so I purchased an adapter from another source and this vent fit like a glove. It fit so well I also installed the model 1200 powered vent forward by the galley [yes, another curved adapter was required]. So here's are a few pics of the rear vent - before internal framing - with the adapter in place on the exterior roof. The other pics are of the Dometic Fan-Tastic 1200 fan completely installed with bracing before wiring. BTW, eTrailer is a gr8 place to shop. Low prices, fast shipping, excellent packaging. What more can you ask? 560347


Still going strong after a full year and no leaks. Just wish we had bought an infinitely variable speed fan. Even the lowest speed is still pretty noisy and draws a lot of air in over the bed making it chilly on brisk nights. Also added an allergy-free filter over the bed using Velcro to the outside of the plastic frame. Plus I replaced those flimsy plastic T-handles with metal-spline window-crank levers [cut down to fit].

Love these can leave your actual crank vent up, and these vents keep the snow and rain out, so you can have good ventilation 719926

Just what I needed to replace an old falling apart roof vent in a 20 year old camper. Looks great and fit perfectly! Nice that it comes with hardware and adjustable depth flange. 639889

Product fit perfect and was easy to ins tall 577042

I have installed two of the non-powered vents and one fan vent. All are well made and easy to use. I just bought another non-powered vent to put where an air conditioner is now. The instruction sheet is obviously designed more for the powered fan model and the experienced installer and will not be much help to anyone who has never attempted to install something like this. 556367

Products (3 vent lids and vent kit) arrived in timely fashion and were the right ones for my trailer. This is the second time we've used etrailer and have been satisfied. Will use again and recommend. Thanks. 545446

Great product and easy installation. FYI—Interior accent frame needs to be cut down if you have a shallow ceiling. 526590

These vents are great! We got one vent and two fans from this company and they were all easy to install and look really high-end in our renovated Airstream! 482914

Very satisfied with the product quality sold at a very fair price. Great value for th $$. Seller was in contact with me from the time of purchase till it’s on time delivery. Vents are being used as a replacement for my work shed skylights. I purchased one standard vent and one fitted with a thermostat controlled, four speed fan system. Perfect fit! It would be great if all my purchasing experiences we like this one! 458477

I love this product! It keeps our van cool and allows ventilation when we cook or have the heater running. It has held up very well too! Highly recommended. 420064

Replaced old original vents that where damaged in a hail storm. These new vents fit perfectly and are much sturdier material then old vents. Good price fast shipping and helpful videos at etrailer. Thanks 384450

We installed the vent today. It fits nicely. It looks good on the inside. We are now ready to camp for a longer period of time......... 378274

Thanks etailer for getting all our products so fast to us . Really appreciate the free shipping. We ordered a replacement roof vent with fan, great product, installed nicely. Couple weeks later realize our other vent was cracked, ordered another roof vent. My husband replace the first one, but I had to install the second one by myself due to him having back surgery. Was able to do in an hour, no problems, and it looks great. Sorry no pictures, I am scare of heights . Sherri-from NV 363980

- FV800900

Bought this to replace a cracked housing that was home to a fan and controls, transferred the fan and controls over to the new body and just like having a new fan. this was all part of a roof repair that turned out to be a roof replace, just like brand new now. 303358


The vent housing is still going strong, saved me lots of money compared to buying a whole new fan, would definitely buy again.

  • Replacement Roof Vents and Vent Lids for 2008 Jayco Octane Toy Hauler
  • Sorry about Mother Nature giving your trailer a beating. We have both complete standard 14 x 14-inch roof vents as well as just replacement lids in many colors and in the most popular hinge designs. If you care to just replace the lids only (and not have to tear out all three whole vent assemblies) you can refer to the linked photo that shows the four common hinge types for 14 x 14 roof vents. Just match your hinge type and then select that one on the page for replacement lids that...

  • Will the Fan-Tastic Vent Roof Vent FV800900 Replace A Fan-Tastic Vent Roof Vent FV801200
  • The Fan-Tastic Vent RV or Trailer Roof Vent part # FV800900 installs in the same size opening as the Fan-Tastic Vent Roof Vent w/ 12V Fan part # FV801200 therefore you don't need to worry about measuring as it will fit your 14" x 14" opening just fine. The measurements can vary slightly depending on where they are taken so the 1/4" discrepancy is not anything you need to worry about. If you don't already have any sealant you can use part # 34427034145-1 for this.

  • Install/Sealant Kit to Use When Installing Fan-Tastic Roof Vent # FV800900

For that we have the Roof Vent Install Kit part # 344270KITW which comes with all of the sealants you would need plus screws to attach the vent.

  • We have replacement vents that should work for your 2008 Forest River pop-up camper. While I could not find a reference to that specific part, most trailer vents fit in a standard 14-1/4" wide x 14-1/4" long opening so you will need to measure to ensure that is what you have. If so, I recommend checking out the Fan-Tastic Vent # FV800900 which will fit roofs up to 4" thick. This vent comes with a garnish and installation hardware and extends 4-1/2" above the roof when it is closed and...

These replacement lids are both designed for the standard 14-1/4" x 14-1/4" roof vent which is what you have, the hinge just needs to be confirmed. If you do indeed have a continuous hinge (see photo) then either will work for you. If you want...

  • We can help you with a replacement vent; since they are universal fits all you will need is the standard 14-1/4" wide x 14-1/4" long opening in your roof.

This fan also includes the garnish and hardware you'll need for installation. I've added a link to a video review of this fan for you to take a look at.
