Question Frig that vents out the roof vent only?

Is it possible to install a gas/elec frig in an AS that does not vent out the wall/side of the trailer and only out of the roof vent?

My 63 AS has street side locking compartment doors which allowed service access. I do not want to cut into my trailer and add a frig vent I can help it.

Or, if I forgo a gas frig and just install a small electric refrigerator, once it is built-it will the vent out the roof suffice? There is also a retangle vent in the belly pan where the old frig was. I was hope to seal that up- As it is an entrance for varmints and road dirts etc... Z.

You could make it work with an electric only refrigerator if you use a fan to move the air up to the roof vent. I would run a divided vent, with one side to push fresh air down, and the other side for hot air to escape back up.

The original electric fridge in my Tradewind had a single vent mounted about chest level. It worked fine for decades.

You could eliminate the vent altogether, but it would turn the trailer into a sweatbox pretty quick.

If you decide to go with a propane electric refrig, your best bet would be to keep the floor vent and find some way to keep dirt and varmits out. In addition to ventilation, it provides a convenient escape for unburned propane.

If you are installing a Servel type refrigerator the answer is NO. This type of refrigerator works on convection, the movement of air up across the back of the unit. This requires a source down low and a vent above. If you look at the installation manual from the manufacture they go so far as to require that the back of the unit be no more than 1 in. off the back wall, something Airstream can not do and it effects the efficiency of the unit.

Installing a household type of reefer in an Airstream trailer, requires the use of the one and only available "large" reefer vent cover, that has been used since 1969.

A small vent cover will cause a household reefer to operate poorly since it would not allow adequate heat to dissipate.
