The investment opportunity does seem to be rare, but I am having my doubts about whether it is a once every 200 years type proposition.. even though it could play out to be that rare..
But yeah, it is probably at least comparable to the telephone, internet, automobile... etc. paradigm shifting innovation.
Regarding that mobile home.. I did not see the price, but probably starts out at about $150k or so, and maybe gets 4 miles per gallon - the diesel version?
The reason I'm saying it's so rare is mainly because everyone could not buy into telephone, internet, automobile, etc... and expect that kind of return on investment. I could be wrong but I don't think so.
As for the price on the Realm RV:
