Chuckh, we use a Honda EU2200i that has been converted to run off propane. Some would ask why? It all comes down to use case scenarios.
1. Ask what can run off propane:
- water heater (when 120v is on this can take 5-9amps)
- refrigerator (if dual not 12v) (when on 120v or auto, this can take 10amps)
- main heater (fan does use a decent amount of amps when running)
- stove/oven/outdoor kitchen
2. What 120v items do I need to run at the same time:
- AC (can be anywhere from 11amps to 20 while running even with a soft start)
- Microwave (can easily run 15-20 amps)
- Hair dryer (these are crazy and will take 25amps on full depending on HD size)
- TV (if 120v, most lately have been 12v) (these are lower amp use)
3. Just remember if something is 12v that it will have some draw on the generator as well when its running as the converter will handle the 12v items. But also know when taking showers having 120v and propane elements on for hot water ensure that you dont run out of hot water but are limited on grey water storage size. So this will take some amps as well if you do this.
We (and most RV'ers) have learned that it all comes down to amps. You are limited by that. Even when plugged into a full 30amp plug you can easily go over amps and trip something. Our Huges Watchdog helps with this and protects us, and allows for resetting via their phone app.
So when we use the generator we just watch it close, if we need hairdryer we turn other things off. If we want AC we just run everything on propane and try not to use anything else so the trailer stays cool. Or we kick on the solar/inverter to do this as well so we dont use/need the generator. But a generator is much cheaper!
With a softstart you can run everything you need, but you usually can never run all of them at the same time anyway. So for convenience and weight we have a smaller generator that only weighs 45ish pounds.
