Interesting. But I swear I've seen Butyl tape used around windows in fibreglass walls. (As well as putty tape around tail light fixtures)

Maybe it's just that you should not use putty tape on a rubber roof? The solvents in the putty might not work well with the roof material?

Cost was a bit less than a Fantastic Fan. It runs on 12 volt with very little draw. I saw the draw at their booth but I don't remember the numbers. It was less than the existing fan and light.
It fit right into the existing range hood (after removing old fan). We kept our same outside vent but could have had a new one. It also has a slide to shut off the 'flue' so bugs can't come in when the fan isn't on and sucking.

We replaced our range vent fan two weeks ago at Winnebago GNR.

We were looking for a Fantastic Fan for our ceiling but came across this booth at GNR- Fabulous Range Vent Fan. We liked this idea due to the three speeds of the fan, and it replaced the noisy jet sounding fan in our range hood cover. On high speed it exhausts our rig. Low speed is perfect for cooking. The light can be switched from bright or nightlight dim. We really are pleased!

BTW the small company is run by the brother of the original Fantastic Fan owner.
(http://www.fabulousoperatingproducts.com/) We had them replace our fan (inexpensive), but it won't be difficult to diy.

That is a very nice upgrade. LED lights with 2 settings, 3 spd fan.
Now to see if it fits, where to get it and how much $$.

I've seen butyl tape and putty tape used on flanged windows and appliance openings. Then the edges covered with a polyurethane type caulk (3M 4000UV marine sealant or a home window sealant) or Geocell.

The picture above was in the construction stages. A metal rod extends through the fold in the flapper, a spring attached to the lower corner of the flapper keeps it closed. I even had a cable attachment ready to use but discarded the idea since it was complicated and unnecessary. IIRC, the flapper seals against weatherstripping, also.
I was a nut about sealing anything attached to the outside skin. I've seen what a leaking marker light or poor window seal will do to a trailer.

Alas, I don't have access to some tin, though I still own a pair of tin snips. I'd pay good money for a permanent flapper like that provided it still stays latched down... material near the corners where the latches attach look a little thin.

When bonding something that has a flange onto an exterior surface (I have aluminum siding) and the flange is held in compression to the siding, I like to use self-stick weather stripping, followed by a sealant around the edge of the flange. Should I have to remove the accessory, later, it is relatively easy to do. The weather stripping makes a good seal and I've never had it fail when held under compression.

What brand of material do you prefer for sealant, that is soft, pliable, and not permanent like silicone sealer for sinks and such. It needs to be removable with a reasonable amount of effort in the future, the plastic does not last indefinitely.

Since the flapper is usually under a hood, any type of caulk could be used. If you don't have a hood, you want something to seal from the elements. I use Geocel tripolymer sealers. It will harden but can be cut with a utility knife.

FWIW, I found the original plastic flapper in pieces. I made a new one , using aluminum sheet goods.
