Fun project! A few things to check before you buy. First, measure the cutout (height, width and depth) and compare it to the new fridge's box dimensions, since older Airstream cabinets are often smaller than today's standard sizes. Second, check the venting. Absorption fridges need a lower intake vent and an upper roof or side vent behind the unit to cool properly. Third, make sure your 12V wiring is heavy enough for the fridge's controls (and DC heater, if it's 3-way), and have your LP line leak-tested after hookup.
The N3104 is discontinued. Our replacement guide shows the current models. The Norcold N4150 is a popular fit for smaller spaces if the dimensions work for your cabinet. Send us your cutout measurements and we'll help you pick the right one.
