We pop-up tent camped for >30 years.
Always dry camped and never needed a generator.
We almost always camp in the fall.
Bought a class C and went on a four week trip.
Used generator twice. Once so current wife could blow dry hair.
The second time to use the microwave.
Class C has solar and we drove a lot so that kept battery charged.
total hours on generator = 0.5 hours.
Now come winter the power went out for three days.
Ran what needed to be run in the house from the RV generator.
Glad to have it!
Next four week vacation will be less driving per day so battery will not get the charge it will need so I'm sure the generator will get some run time.
Still like to dry camp.
Agree with everyone else, would not buy a RV with out a generator.
