A good place to look and there is a bunch to compare to and diffirent prices. $900 does not buy much.
I spent considerably more for a generator to power the trailer and or some of the house in an emergency. I got an 8000 watt. More than enough to run a refrigerator, freezer and the RV AC.
Keep in mind if a $900 dollar generator does not do what you want then it is a waste of money.
Research what you
need then look for price.
