Airstream electrical system upgrade: Phase I
The electrical system that our 2018 Airstream Sport 22′ camping trailer came from the factory with was pretty basic. It had a single open cell lead-acid battery capable of powering the lights, the furnace blower, water pump, stereo, and a few USB outlets. However, it didn’t come with an inverter, needed to run any AC appliances (microwave, toaster, blender, etc) while off grid. It also came with only a very basic voltage-based battery monitor that doesn’t give much information about how much battery capacity is being used or is remaining. In this post, I’ll describe the first set of electrical system upgrades we’ve installed in the trailer.
