Fridge chimney- '66 Caravel


i' currently gutting our 66 caravel ready for a frame off resto. i was wondering about the fridge exhaust that runs from the back of the fridge out to the vent in the roof. its pretty broken up around the edges where its riveted to the interior skin. As i plan on updating the fridge to something a bit more modern, i was wondering what the new ones need to vent. do they still need the great big foot wide plastic chimney or can i replace this with something a bit smaller, as the old one is probably shot anyhow.

The newer trailers are designed so the refrigerator goes in a cabinet and eliminates the "chimney" inside the trailer, but it's still there in the cabinet.

If I were you, I'd do everything I could to salvage yours, even glue it back together, and use it as a plug to make a mold, to make a new fiberglass chimney. The refrigirator has to have this to get rid of the heat, and heat rises.

Fridge chimney-66 Caravel

New fiberglass refrigerator chimneys are available from Inland RV. My understanding that some tweaking may be required for a perfect fit, but that it is a comparatively easy install. See this link.

Good luck with your project!

Instead of a chimney, new fridges have an exhaust vent in the side of the trailer. While this would require cutting a hole in your skin, it would be nice not to have that chimney taking up counter space and pretty much wasting that cupboard above the counter. So if you're doing your own thing and aren't worried about originality, I would go that way.

I would not cut another hole in your Caravel. The fridge is so low already that the opening would be virtually ineffective. Make or buy a new chase and install it. It give the fumes and heat a chance to build up some velocity as it exits.

While not exaactly what you were asking about, before you install your new flue and fridge would be a great time to put in a small computer fan to help get the heat up and away from the fridge.

Our experience

Caius -

Great to see that someone else is doing a full monte on a Caravel!

We have over 100 days of camping in ours in the last two years and have had no problems with our Norcold N300 fridge and fiberglass replacement chimney. With the small fridge and tall chimney, we always had good air flow and didn't have need for a 12v fan.

Be careful when you measure for a fridge. The distance between the door and wheel well is small on a Caravel. We couldn't go larger than the N300 and, in fact, had to raise it off the floor to get the width we needed. (Wheel well arcs towards the rear, increasing the distance between door and where the bottom of the fridge intersects with the wheel well).

BTW, I really like the fact that there is no parasitic draw on this model. Some fridges require a fair amount of DC power to monitor the flame.

First, check the price of the new vent and you may want to fix the old one. After seeing the price of a new one, that is what I did. I used West System Epoxy and fiberglass cloth to fix the edge that were severely cracked It took several steps and some sanding but I saved a lot of money. The vent is hidden inside the cabinet on my Trade Wind so it did not have to look perfect.

I installed a new Dometic fridge in my TW. The instructions were clear that you need the vent stack so that the convection currents would pull the hot air upward. Also, the new fridge needs to be sealed in the cabinet (foam tape) so the air flow will be from the vent at the bottom and up thru the chimney. The better the convection the more efficient the operation. I took great care with mine in that regard and was getting below zero in the freezer compartment this summer on 95 degree days. You can go to the dometic web site and download installation instructions. (New fridges are not cheap)
