I’m installing a gas refrigerator in place of a missing one. Any concerns?
The biggest would be ventilation. Early Airstreams didn’t provide adequate ventilation for the cooling tubes. When it comes to refer venting, the key is “draft”. The taller & tighter your chimney, the better the draw of cool air over the coils of the refer. The ideal is a screened intake in the floor (what Airstream started using in the ’60’s), into a relatively tight compartment made using the refer back, side cabinets & outer wall of the trailer, continuing upward and exhausting out the top of the trailer. The top roof vents used in the 1950’s looked more like smokestacks, and are still available at better home centers, hardware stores, and plumbing/heating supply houses. They have both the 4″ round capped ones, usually used on the heater vents, and the long oval one, usually used on the refer’s. Both have storm collars, made of aluminum and look much like the ones from the ’50s, only now made in Mexico.
