I use a single Champion 3500 watt Dual fuel Inverter generator. I run it only on propane. It easily powers all my loads on my 30 amp Airstream.
I went with a single generator for convenience and a bit of extra capacity. It stays in my truck bed. I modified the generator propane regulators to make it easy to connect to the Airstream propane system. The modification is shown below. Basically unscrewed the two regulators from each other and added quick connect fittings.
High pressure OEM Champion regulator with a female quick connect added. This lets me run from a stand-alone propane tank if I want to.
Low pressure OEM Champion regulator with a male quick connect added. This is required to connect propane to the generator inlet fitting. It regulates propane flow to the generator carburetor. The quick connects let me use one or two 12 foot long extension hoses as seen in the background of the picture. The black hose at upper left is the OEM hose that goes to the Champion’s propane inlet fitting, and it must not be modified.
3/8 quick connect and shutoff valve on A-frame if the Airstream. This is where the hoses connect. The valve is needed to shut down the generator and let it burn any propane in the hoses and regulator for safety.
The Champion is much less expensive than a single Honda, and cranks out more power. It also has a 30 amp RV outlet built in. No dog one adapter needed.
Yeah, it weighs about 90 pounds, but I load it into the truck just once a trip. It runs on the tailgate when I need it. I’m a certified semi-retired old phart, and I can still lift it in and out of my Tacoma as needed. It’s a lot lighter without gasoline in it.
The ‘clean output’ is a reference to the shape of the AC output. Clean means it is very close to standard AC power. Some cheap inverter generators put out a ‘modified sine’ power that is not good for sensitive electronics in an Airstream. The Champion puts out clean power.
The Champion Dual fuel 3500 watt inverter generator is used by many folks on the forum and so far has been shown to be reliable. There is service available.
I suggest adding an hour meter to the generator for tracking when to change the oil, and a wire harness to connect a battery maintainer while it is in storage to keep its 12 volt
starter battery charged.
I have an EMS/surge protector built into the Airstream for power protection when plugging into shore power. For use with the generator I have a ground to neutral bonding plug installed in a spare outlet on the generator to make the RMS/surge protector ‘happy’ when I run the generator. The EMS requires proper power connections, voltage, and ground to neutral connection before it turns power on for safety.
I also added a front power inlet to the Airstream for ease of connecting the generator and a manual transfer switch to select the inlet power connector.
It’s also possible to add a MicroAir Easy Start module to the air conditioning unit to make it possible to run it on a single 2200 watt Honda generator with a propane conversion. This can be marginal at higher altitude and on hot days. I went with a 3500 watt generator to accommodates wider range of conditions. I did add an easy start module anyway. Makes the air conditioning compressor start more gently.
Fell free to ask more questions if this is not making full sense to you. There are lots of folks on these forums that use quiet inverter generators for camping.
