Back inside I spliced my wires I had run through the channel into the fan wires. Pulled everything tight using the other end of the wires hanging out of the cabinets, then called it a day.

Until I know for sure whether I'm tying in to these wires in the cabinet, or doing something else, I'm not going to trim the wires.

Not as nice as some stained wood trim, but it'll do for now. Maybe I'll do something a little nicer down the road. So to speak...

Good job, looks great.
On those two problem screw holes: a standard carpenters' trick is to tightly fill the holes with wooden matches and then screw into them. It really works well.

Looks good!! I think you will be very happy with the fan.

You may want to consider using a heat shrink on your wiring connections in the future. Will stand up to the travel vibration better then most connections and protects the connection in the event of water/damp.

Thanks.

That's a great idea! Next time.

Yes, you're right.

I know better...but I don't have a heat gun, and in the past used a lighter to shrink the heat shrink...with not so good results. Just as easy to burn the stuff. So while I know that's the "right" way to do it, it isn't happening for me right now.

Once in a pinch used a hair dryer and it actually worked.

I'll own a heat gun before I own a hair dryer.

But also when I look at how Bigfoot themselves wired stuff...they just used connectors with no protection at all. No tape, no shrink wrap. Nothing.

Not that that's a good thing...

LOL Bigfoot is not the only ones, so do many/most of other trailer manufactures..... but its that one time that some connection 10 years down the road manages to come just a little loose that is hidden away someplace that will have you pulling your hair out trying to find the cause as to why something works sometimes and not others.... most of us with older trailers have been there done that!

Nice job. You can hopefully see how a shop did ours in the picture below. Sorry that you can't really see but a corner of the fan, but this is a crop of another photo and it's the only pic I have that shows the ceiling at all really. They tied into the ceiling fixture and used "surface wiring" covered with a cap to hide the wires. No need to fish wires through anything, but yours looks better! Sorry I didn't see your original post earlier.

Looks great Kathy. I would have actually preferred to tie into that light. I think the circuit it's on only has that light and the other light over the front dinette, so it definitely has room for more amps going through it.

The wires in my last photo of the wiring post are what I'm looking to tie into to, and as you can see from the photo, they're already spliced and quick-connected. And I think there's a lot more on that circuit, like the range hood fan and monitor panel. My new vent "manual" doesn't even say how many amps it pulls so I'll need to look that up to see if feel comfortable tying into those wires.

I like your wood paneling! Looks like some years they used a bit more "interesting" wood than others. Or maybe it just depended on what happened to come into the shop that day.

Thanks Rick. I'll get up there with lap sealant today and they we'll see. Rain forecasted for tomorrow so it's time! Unfortunately I'll be out of town so I won't get a chance to see if there are any drips.

But where the flange is around the fan on the roof, I definitely got all the old silicone removed. Then two layers of butyl tape and I definitely had some squeezing out all the way around when I tightened it down. The old lap sealant I was too lazy to clean up starts just outside of where the butyl tape under the flange ends, so I think I should be good.

I will let you know.
