I bought a generator that did not cost a lot but would provide me with power to run the RV using the air conditioner, also provide me me power in case of a power failure at home or work. I have thought about if the power goes out at home I am going to live in my BH, but then I may need two generators (one for the RV and one for the freezer and frig at home).
I wanted the Honda but since I won't be using it much the extra cost changed my mind to a lower cost product that will do the job, with more noise. The one that TDHarley had a link to looked very good.
I bought one from Cabela's for $399 "the description is shown below"
