Windmill usage
I am looking at a small windmill to use on my property while living in the 5th wheel. Eventually we will be building on the property but until then I am looking at this as an alternative. I have a ...

Unless it's a really windy place, I wouldn't count on it. That's about 12.5mph winds but keep in mind, power output goes up with the square of the speed. Drop back to 6mph and you don't cut the power in half, you might not even have enough to get it spinning. At high wind speeds, many times, the windmill has to be locked down to avoid damage.
Then you need a battery bank that can store enough power for a day or two of light winds.
A typical RV air/con pulls about 10-12amps in operation. So let's say 22amps when it's hot at 120v for 2 units and assume a 50% duty cycle. That's 2.6kw when in operation or about 32kwh over a day. Even if they produce the very optimistic 5.5kwh per day, you are going to need 6-8 windmills...just for the air/con.
Add in 3 tvs, 2 computers, 2 fridges, etc...etc...etc... you are probably up around 10 windmills...IF you can really get 5.5kwh out of each.
Not meaning to be harsh, but unless you've left out critical information, you aren't even in the ball park.
