Everyone full-times differently so you'll have to figure out how you want to do it.
We used public parks or boondocked 90% of our 16 years of full-timing. We had a 40' motorhome towing a Jeep which gave us lots of fun on the backroads. We had no problems fitting into national parks or forest service campgrounds. . . also state, county and city parks. We had no qualms taking it on well maintained gravel roads for boondocking.
We had solar, big holding tanks (could last 12 days or so before dumping), no dishwasher, no washer dryer (went to the laundry in town every 10-14 days and got it done in 1-1/2 hours and did our errands at the same time), only one bathroom and only a small canvas bag of tools.
It was an easy, uncomplicated lifestyle. Good luck to you!
