In 11 years of retirement camping I find myself doing 3 routines. Travel camping, going cross country, Canada, Alaska, snow birding, will search out NF, SP,COE, NP or other remote CGs and stay from 1-4 days and explore surrounding area with the tow car. I have never stayed more than 7 days in one spot. Fishing camping, where I go locally for a couple of days either by myself or a friend. And family camping where we will travel maybe in a 300 mile radius from the house and camp for a week. 95% of our camping is dry camping. Batteries last 7 days before getting down to 50% SOC, FW last 7 days(60 gals) and clothes and bedding must be washed after 7 days. When traveling I stop at a FHU CG every 7 days with laundry so we can do laundry,recharge the batteries,and get FW. I find myself wanting to move on after 4 or 5 days unless there is a lot to see in the area. Quartzite was interesting but after a week I wanted to move on I would not stay there for the whole winter. To answer your second question is I don't do this for financial reasons it is just the way I like to camp. I would not own a MH if I had to stay in RV parks. To answer your other question I don't return to the same places year after year I try to got to new places when traveling. The only place I would like to return to would be Alaska but It would be more of a fishing trip and less off a sight seeing trip.
