50 States x 100 skoolies = 5,000
50 States x 200 skoolies = 10,000
50 States x 300 skoolies = 15,000
2018 RV ownership in U.S. was ~480,000
U.S. Population 2019 - 328M
U.S. Population over 18yo - 78% of 328M = 256M
Percentage of Adult American's who own RVs 480k / 256M = .002
Washington state has about 4.8M adults x .002 = 9,600 potential RV owners
1% of 9,600 = 96
DIY, Irreverent hippies, those who can't afford a commercial diesel pusher, etc.. Do I think out of 9,600 potential RV owners in WA state there would be 96 skoolie owners? Yes, I do think so.
Seems to me, there are easily 5,000 nationwide. 10,000 wouldn't surprise me.
Now that that is inconclusively not solved, how many licks does it take to get to the center of a Tootsie pop?
