Installing an RV roof vent/fan

Recommended Posts

Has anyone installed an RV roof vent on a TC Wagon ?
Since I can't see the structural ribs... I'm afraid of doing any cutting. 

Ant ideas ? 
Of is it too much trouble and not worth the effort.

A roof vent would be great no doubt, but is it necessary is the real question. Your van already has several opening windows which puts you way ahead of the non window cargo vans like I have. I added one opening window in the R slider which also solved a blind spot issue. Then using screens and a fan I solved my problem with condensation issues inside from overnight sleeping. I am not knocking a roof vent because it would work great. I did however solve my venting issues without cutting a big hole in the roof.

Here is the link to my simple camper van:

I think it only takes a little hole in the roof.  ;)

The Maxair vent I installed requires a 14"x14" hole.

"Maxair" sounds like that might not be the standard size.  ;)

Some thought should be given to placement.I know centering looks the best,but if you ever plan on purchasing a roof box like Thule or Yakima 

( I have one and they're great),you will need to offset the location.

I used this adapter to level out the mating surface available on Ebay. The adapter worked very well, but you want to plan out where you might have solar panels or roof storage like Jack said if you're planning on going that route first before locating the hole for the fan.

ALL roof vents and A/C units are standard 14x14" hole size; Maxxair (two x's) is simply a manufacturer brand name.

Mine need a 5x8 foot hole if I remember right ...  ;-}

... and ya ... that is a MaxxAir fan, and measures 14x14. One word of caution - put the remote in a safe place as the built in control panel sucks ... not a bad idea to add the batteries for that to your annual list of things to do.

 

PS - if the type two's are anything like my 2011, there's only one support rib between the front and rear doors. You can see where mine was cut out for the pop top.

My Gen 2 LWB has 2 support ribs in the roof; one right above the driver/passenger heads and the second is about halfway through the cargo area.

Same as the gen one's then. No need to cut the front support as I don't need the extra headroom over the front seats, and it makes a nice reinforcement for a cargo area between the original roof and topper for light duty storage like blankets and such.

You will need to measure the dimensions of your existing fan carefully. Although most RV vent fans are 14-inch x 14-inch, you should measure it again just to be on the safe side. You will need to remove the knobs and screws that hold the fan’s plastic shroud inside the recreational vehicle. After removing all the screws, the cover should just drop down. You just join them using clips to not even strip and join the wires later. Set the power supply wire aside so that it will not get in the way of the new fan, but make sure that you can still reach it later. This is the ways I installed my rv vent fan. If you need detail information, I will help you.
