I guess moving twice a day is ok, but we don’t full time. We are usually sightseeing during the day and almost never staying in the TC all day.
I do occasionally park in a relative or friends driveway although I’m usually inside visiting except for sleeping. On a recent trip, we parked in a relative’s driveway one night, stayed at a State Park, stayed at a wedding venue that was also a campground for free, and stayed at a close by RV park to the airport since my sister had a 6:30 AM flight. We spent less than $100 total for spots and that counted the expensive close to the airport site. Not much considering the cost of fuel for those days of driving/sightseeing.
For the expensive site, we only used the showers and bathrooms. I never plugged in since we were going to leave so early (around 4 AM). I wanted to minimize disturbing my neighbors. We charge plenty while driving.
