that seal has to be there to keep water when driving from getting thru..... the four inches i get on each side window works good with the fantastic fan up top..... you can always trim that rubber edge back some which i think would work when you want to fully open it but in the stock position it is great for keeping rain out.

I'm getting this product!

But ... I do believe that the MaxxVent engineer I spoke with told me that the WindowMaxxVent works great with a roof exhaust fan. What's important is the location of the vent with regards to the roof fan.

So, to answer Nancy's concern: I don't think you would really need to completely open any window that has this vent.

Thumbs up

Hi Everyone with MaxiWindow vents:

I did purchase a couple of MaxAir Window Vents. We've been waiting for dry weather to install them.

I do have 2 questions:

Question 1: Did you have any problems/hesitation drilling holes (for rivets) into the fiberglass around the window frames during installation?

The reason I am asking is my husband was very worried about drilling holes. I saw on the Casita site that someone used VHB tape. I was wondering if any of you considered such an alternative to rivets, or if we should feel free to "drill away".

Question 2: Am I correct in assuming that I can completely close and latch the windows when underway? I would not want passing trucks to spray water sideways and into the trailer cabin as we travel along on a rainy highway.

Thanks for your replies.

JMP

The window frames on my Scamp are metal and I had no hesitation about drilling holes for the Window Maxx's. Just don't drill entirely all the way through into the cabin of the trailer. All you are doing is attaching the plastic louvres to the frame. Mine came with several different lengths of bushings/spacers that the screws go through. You simply have to use the ones that snug the Window Maxx against the frame. Not too tight as you could crack them. It's possible that you might have to use different length screws than what came with the product. All windows are a little different.

Here's a caution. It's the middle piece that you have to cut to length. These Window Maxx's are made to fit very large windows so you have to cut the middle piece to size. Just be careful to do one window at a time as you'll be inverting the opposing side. You don't want to make a mistake in the cutting.

Yes, of course you can close your window. The Window Maxx doesn't inhibit normal operation of the window. It simply allows the covered portion of the window to be opened up to 4 inches without rain coming in. And, the window may be opening in it's entirety if you choose. I always close and latch my windows while traveling.

There's no real need for a vent fan unless you want one. I have one but most of the time I just have the windows cracked without the fan operating. If it were raining rain would come in the vent fan. I don't have a Maxx Air cover over my vent fan, nor do I want one. I wouldn't be able to put my Scamp in the garage.

Jane, I just noticed this thread or I would have commented sooner. Several years ago I bought a '97 Bigfoot trailer that had come from the factory without an air conditioner. When I decided to add one, the roof vent was the only logical place to put it. As it turned out, the trailer had 110 wiring up into the adjacent cabinet, so the roof opening was intended as either a roof vent or air conditioner opening as per customer preference. If the trailer had been ordered with air conditioner, then a second opening would have been cut for a roof vent. I considered cutting into the roof to add a vent, never did it. Instead, I put a Fantastic Fan in the bathroom roof vent to move air through the trailer when needed. I put a Maxxair II vent cover over that vent to keep out rain. It worked just fine.

My current Bigfoot does have both air conditioner and a roof vent in the cabin area. I have covered that vent and the bathroom vent with Maxxair II covers with excellent results. I also have a Fantastic Fan in both vents. The Maxxair II covers move plenty of air but have never let in water. The reason I went with Maxxair II is because they will fit over the bathroom roof vents in Bigfoots in spite of the holding tank vent pipes being very close to the roof opening.

I have often thought it would be great to have at least one window with a rain cover, too. I will probably pursue that next. During wet weather, you need ventilation more than ever.

Thank you so much for your post! It looks like you have answers to some future MODs for my Bigfoot:

What model/size was your '97 Bigfoot? Where would you cut into the roof to add a vent: in front of the air conditioner, or behind?

Where is the roof vent located in the cabin area of your current Bigfoot?

Can you send me a drawing?


Regarding the fantastic fan: Even though it's a little more expensive, I'm thinking of eventually installing a Maxxair fan and vent in the Bathroom - I like dealing with the company, and it seems like the complete system is a little more efficient.

I need to hit the road with the trailer to see what sorts of changes will provide additional comfort. If I really enjoy my Bigfoot journeys, I will begin to add some more Mods. Based on my experience of sitting it other peoples trailers, I do think that I would appreciate a fan in the main cabin.

Regarding the Maxxair Window Vents: I haven't had an opportunity to test out the vents, but they are fairly inexpensive and easy to install. Everyone I know who has installed this product really likes it.

I am looking forward to getting a better understanding of where to install/wire a fan vent in the cabin.

My 97 Bigfoot and my newer one are both 21' rear bed models. My current trailer has the vent opening directly over the bed. Given a choice, I would probably have preferred that it be located further up front. Like you, I do like to have a fan-powered vent in the cabin area, not just in the bathroom. I am not familiar with the Bigfoot 19, so I can't really advise you on the best place to locate a new vent in your trailer. I never could quite bring myself to actually cut a 14" hole in the roof of my '97. That trailer also had a skylight where I would like to have put the vent, but that is another story. One reason I don't like the vent over the bed - if it ever leaks, there goes the mattress. But a good vent cover should prevent that. If I was you, I would keep quite a bit of space between the air conditioner and the new vent opening so you don't weaken the supporting ability. That air conditioner weighs around 100 pounds.

I don't know how to send a drawing on this forum, but you can look up the floor plan of the 25B21RB on the Bigfoot Industries website. You can see where the bed is located - the vent is right over the bed on this model. But it would make just as much sense to me to put it over the dining area at the front of the trailer. I wish you the best of luck with whatever you decide.

Thanks Dave.

I'll probably pass on cutting a hole in the cabin roof, unless the Bigfoot people assure me that would do no harm. The Bigfoot 19 is just like the gaucho model Bigfoot 17 -- only 2 feet longer.

There is a very big difference in the floor plans of the 19 footer and your 21 foot trailer.

Thanks again for your input.

I don't blame you for being reluctant to cut a new vent opening. You should be able to move enough air with the bathroom vent and open window in the cabin. My 97 Bigfoot had a bathroom door that did not have any air space around it. So I could only draw air from the cabin through the bathroom fan by leaving the door partially open. I solved the problem by cutting a vent in the wall between the bathroom and cabin. I put a louvered vent cover over the opening to finish it. Sorry I don't have a picture of that project for you. Later model Bigfoots have a bathroom door with lots of air space at the bottom.

My 1986 Bigfoot 17 Gaucho has Coleman Roof Air added about a year after the trailer was built. It is on its own circuit. After I bought the trailer I had a Maxxfan installed aft of the a/c, to replace an existing 14" roof vent. I'm guessing the installer just grabbed power from the bathroom light. Anyway, the Maxxfan works quite well to exhaust hot air on a hot day. When it rains not too hard I use the bathroom vent as the input of fresh air for the Maxxfan to exhaust, since I don't mind a few raindrops in the bathroom. After reading the posts here I may get a Maxxvent for one of the forward windows. My only criticism of the Maxxfan is that the design may admit the occasional mosquito and all the no-see-ums.

Wow! That is interesting info! Have you actually had mosquitos and/or no-see-ums enter your trailer or someone else's via the MaxxFan Unit?

Come spring, my trailer will be located in areas visited by lots of mosquitos and no-see-ums. They love me almost a much as I hate them! So it would be important to me to keep them out of the cabin.

Just when I settle on a product, someone on this forum brings up something to ponder!

Indeed, no-see-ums enter through the MaxxFan, as they will through any opening only protected by standard screening. Poison is available to paint/spray on screens for keeping out the little rascals. I plan to keep them out by attaching no-see-um netting [available by the yard from REI] to the MaxxFan trim piece [called a garnish, don't ask me why].

As a proof of concept I have covered the MaxxFan opening by taping no-see-um netting to the MaxxFan garnish, leaving slack in the netting so that I can operate the fan controls. As it turns out, this does keep out the no-see-ums.

When I get around to it I'll pull the tape and glue strips of velcro hook to the perimeter of the garnish. [Note to self: The proof-of-concept tape did not stick well in humid South Florida. Find a tenacious adhesive before attaching the hook strips to the garnish. Do not rely on sticky-back velcro, which caterpillars after a while.] Next I'll have velcro pile strips sewn/glued/stapled to a piece of no-see-um netting so as to fit the garnish. Then, since it impedes air flow, I can install the no-see-um netting only when necessary. I am planning a similar application for the bathroom vent and a couple of windows.

As far as mosquitoes getting in through the MaxxFan--yes they do but not very many it seems. The MaxxFan removable screen is held in place by four plastic hangers. Enough space exists around the hangers for small mosquitoes to enter.

This was demonstrated during the no-see-um netting test, which took place in the Flamingo area of Everglades National Park recently. After a couple of warm humid buggy days, in addition to lots of no-see-ums, a couple of mosquitoes had gotten between the MaxxFan screen and the no-see-um netting.

I wouldn't let the insect issue deter you from some kind of powered fan in the ceiling. Without it, our Bigfoot would be unlivable on hot days. In addition to the MaxxFan, we run a 10" O2Cool fan, about $14 in the camping section at WallyWorld, to blow air right on us. This fan is made to run on batteries but also has a standard 12v input, so can be run from a 12v socket using a standard cigarette lighter extension cord [Radio Shack or thrift stores or maybe from your AA battery charger accessories] or from 120v using a transformer with 12v output [my AA battery charger transformer works just fine].
