The other part to consider is that while you HAVE everything in your RV you are limited by tank space.
You might want to use the campground facilities more often than you expect, so you don't have to empty/refill your tanks as often. For example, you may want to limit your personal toilet use to in the middle of the night, but use the campground toilets during the day.
If you're going for a self propelled option, then you'll also have to think about how you're going to access places you're used to driving a regular sized vehicle. On the road, you may not fit through the drive thru. If your campsite doesn't have walking access to the sites you want to go to, you may run into issues parking your RV in regular parking lots, some of which may be gravel, instead of fully paved.
Ultimately, it's not a bad idea, but traveling with an RV does have a learning curve that I imagine will be more difficult to adjust to amid pandemic restrictions. For example, my parents first big trip out in their RV, they ran out of propane more quickly than anticipated. It was winter. Fortunately, they were in Georgia, so the nights didn't get TOO cold, but it was cold enough that they got uncomfortable.
You may be more comfortable looking into extended stay hotels, cabins, or somewhere else with a kitchenette etc and just doing a solid clean as soon as you arrive, then reject housekeeping for the duration of your stay.
