Most Popular 4-1/2 Inch for Van

Ventline Ventadome Roof Vent 14 1/4X14 1/4. Shipping was prompt, product arrived intact. Had to get the #10 stainless screws to install (expected them to be included) plus the butyl tape and lap sealant which I knew from the description I'd need to buy seperately. The install went without any issues. I was expecting it to fit with no trimming but ended up needing to trim each corner on my 14 1/2 inch opening. My roof thickness was right at 1 inch so needed to trim down the trim strip. How will it do in a driving rain? To be continued.....

This vent is well made and assembly was very easy. Installed with a liberal bead of flex seal caulk and flex seal aerosol as final sealant.

Product description, fitment, construction materials, size, all matched the website. Very good product for replacing your vent on a trailer. Excellent support and shipping from company.

Installed this vent into my Haulmark Transport 6'x12' enclosed trailer. Installation was easy, I cut a 14.25" x 14.25" inch hole between two crossmembers in the roof and dropped it in place. Because the roof on this enclosed trailer is so thin, I used a piece of 3/8" plywood so sandwich between the interior garnish and actual vent. I cut the same size hole into the plywood and left a 2" lip all around. I use 28 #8 x 5/8" stainless screws to hold it in place, pre-drilled with 1/8" bit. I then used roofing tar to seal the vent and put masking tape all around, leave 1" from the flange to ensure good coverage. I then removed the masking tape, leaving nice clean lines. Interior garnish is held in place by #8 x 3/8" galvanized screws. Huge kudos to etrailer for carrying such awesome products for great low prices and offering super cheap shipping to Canada!

The 2250 Fantastic Fan still working great after a year! Pretty quiet and the thermostat is a handy feature that works well. In my application, it has a tendency to open itself while driving around unless it has been cranked down fairly hard. Driving with it open doesn't seem to be a problem other than the outside noise that comes in that way. My application was a fiberglass raised top on a Chevy van. I had to make a wood frame as the fiberglass did not provide a flat surface to mount to. Photos below show inside frame, fan, and insulation.

Excellent unit, does what we require. Replacing really original units that were installed on my old Airstream

My order arrived more quickly than I expected and in good condition. The included single piece of paper (instructions) are absolutely useless. If you haven't done this before, watch a video or two before you start. My vent now works and I'm a happy camper. etrailer came through again!

This fan has worked great for my motor home. If you need a stronger breeze, this may not be the fan for you.

The (2)fan lid black plastic mounting bosses broke as if they had deteriored in the sun. This lower the lift arm to flop down and keep the lid from opening. Trying to figure a method to repair.

This powered roof vent is great! I mounted it above the cab in my 1991 high-top conversion van to provide cool air when camping in it. Fan is more powerful than I expected! I rarely need to switch it to high speed. It's quiet enough for sleeping just a few feet away. Installation was easy and dimensions were accurate. Controls are easily accessible. Auto temp control is really nice when outdoor temps are dropping during the night so we don't get too cold. Rain sensor triggers to close cover after only a few drops of rain! Reversible fan is nice.

This part was a direct replacement for what was broken in my toy hauler. It was easy to install and I have had no concerns since it was installed.

I’m writing this review before installing the vent so I can’t attest to its durability/longevity. This is a lightweight unit but it should suffice for use about three times a year for a couple of days at a time. This unit is affordable; well under $200. It is a next step up from a passive vent with no fan.

Installation was easy and a perfect fit for my 2021 Airstream 16RB (replacing a 3 speed Fan-Tastic unit). I like the speed range of this fan, and how quiet it is when set to 50% and lower, big improvement. However, all the other features (rain sensor, temperature setting, reversible direction), not so impressed with. I don't like the fact the fan turns on at full speed every time I switch on the battery disconnect (applying 12v power). Why is this necessary? I also have a hard time determining which direction fan is pushing air (pulling air into the trailer does not produce strong air flow), and maybe the vent cover is preventing good air flow. It would be nice if there was an LED on the remote or unit to indicate direction (forward or reverse). I know that sounds silly, but I put my hand up to the unit and can't feel which direction the air is flowing, it's just moving around. I ignored recommendations to go with a Max Air unit, and if I had it to do over, I would install a Max Air instead with built-in cover. I may even do that anyway just to have a better fan and cleaner look.

This was a great addition to our trailer. This is a remote control model because the ceiling is too high to reach from floor level. With two high volume fans we can circulate a trailer full of air quickly. I wouldn’t be without a fan like this.

Vent was easy to install, really didn't need the instructions. I would have appreciated a template for the hole though. That way I can just throw the template up and cut along it. A recommendation to reinforce the underside with something (I used 2x2s) might be helpful as well. You do say to align it with a joist, but who's really going to have multiple joists within 14 1/2" from each other? Otherwise, it looks great. I figured you have multiple images of the vent itself so I figured an image of how I reinforced it would be the most helpful for future installers. Thank you. Aaron

Product material and build is solid. Easy to install. I like the smoke colored cover, lets in the right amount of sun (we dry camp in the Southwest a lot). The fit between screen and frame with the open/close knob was off by about 1/4 inch in depth. Was able to adjust the knob mounting position down so as to insure a tight fit between screen and beauty ring. We have an eighteen-year-old rig, so it is challenging to find replacement parts that fit as original. But it fits great now! great web site - easy to drill down to appropriate parts. Thanks again.

The ventline roof vert is just a little better than having nothing. I installed it to fill the hole where a RV roof air conditioner was. The fan motor is very weak and does not move hardly any air. Also the plastic cover that cranks up is very light and is not heavy enough. It vibrates awful going down the highway. It is very annoying. No way does it compare to a fantastic fan that are in RVs. But it did fill the hole from the air conditioner.

Excellent service arrived quickly, just as I had ordered. Thanks

I received the product today. Customer service to this point has been excellent. It will be about a week before trailer repair folks will be here to install, however, I did open and inspect the product. It was not protected in the box and is wedged into the box. I pray it will not be damaged.

Good replacement product for my RV power vent. Fast shipping too! And a great price.

The vent arrived on time. When I had a question about cutting it to fit the thickness of the rv roof, I was given good advice in a call to etrailer.

I was expecting a larger trim, probably should have read the description better.

Fan arrived in good shape on schedule. There were no wiring instructions or mounting hardware

I am very pleased with the quality of the vents. The prices were good too. Very happy with my purchase and how quick the vents came. Thank you
