My Cruiser was most likely a park model being entirely 110v. I am not sure (as many on this forum probably are) when 12v
systems were introduced into Airstreams, but I know mine had nothing of it.
A few months ago my original refrigerator gave up the ghost. It in all purposes is not a well designed fridge just a glorified ice box with a condenser unit. But it is original, and has a great feel and look to it. It is a Marvel, as seen below:
Since that fridge stopped working I have been considering my options. I do not like a propane option because I do not want to add another vent on the street side, but I would love a 12v
mode for camping and on the road. But then I really wanted to keep the fridge, but I believe our sailing friends have an excellent solution actually produced by Dometic.
Custom Cooling Kits - Dometic
Dometic bought the Adler Barbour company, which has been around for many years now and are known for their reliability, especially the units using the Danfoss BD50F compressors. These systems run exclusively on 12v
and for a 4.5 cubic ft. space use about 40-50 amps per day (varying on application and evaporator unit)
I will probably do this conversion for a number of reasons:
1. it uses quick connections that allow for DIY install and you can even disconnect the unit from the evaporator without losing charge
2. it uses r-134a so if it ever needs recharged it will be a quick run to autozone
3. They are made for boats so they can handle movement and will work on a tilt.
4. it comes pre-charged
Now the cost will range from $800 to $1000 but for a r-134a 12v fridge that I can install and service myself, with a large community of support and parts, and that saves my original fridge; I find that to be a mighty good deal.
I still have a few questions to answer but I am pretty excited about the alternative. I know a few of the Cruiser guys may be excited to hear about this.
