As I read,, I wonder why?

100 years of research,, and testing ,, with millions of trailers made of all shape and sizes and millions upon millions of miles on the road there is a reason why Wally built trailers along with all the other SOB company's with a 120v AC and 12v DC systems.. It works,, gives flexibility,, and each system have a time and a place and reason of service.

What one might save on one end doing without will be lost on the other.. A converter is not a high dollar item,, and if the weight is an issue one can just scale back the size of the storage battery..

Depends on what you are planning to do many of the systems in the Airstream require 12VDC to operate.

Air conditioning, microwave, TV and converter require 120VAC everything else runs on 12VDC.

You don't have to have a battery since a converter provides 45 to 80 amps of 12VDC.

However "not all" converters will operate without a battery but you do need 12VDC.

I have a Progressive Dynamics converter (60 amp) the manual states that it will work without a battery.
