I saw a wind turbine set up in Quartzsite, and it was LOUD! Probably not as loud as a contractor generator, but maybe if the wind was blowing a little harder?
One problem with a wind generator is they tend to make a lot of electricity when it is windy, and most RV's don't have a 500+ pound battery pack to store all that energy. . .
Many home wind generators have a 400 watt electric element going to the water heater, and have a 50 gallon (400 pound) water heater to store the excess energy as heat.
It is much easier and quieter to run a 500 watt solar system, that will produce the energy that you need, any excess will not have to be saved or used, and the cost is now very reasonable.
