Had a buddy who spent a couple years in a similar setup in the mountains year round. Wasn’t even a cab over. It was best described as a crude shelter.
He fared just fine save for the one night he came home from the bar, lit the little propane radiant heater (the type that screws onto a little green propane bottle) and went to sleep. Woke up to the heater out, went to light it and BOOM. Blew the door off the back and his eyebrows were missing!
He routinely maintained a gym membership where ever he was living. Mainly for the showers. Seems to be a common workaround with other folks I’ve known with similar arrangements.
If she’s smart and resourceful, I’d say go for it. No time like the present. When you grow up, you can’t do that fun stuff anymore.
Good call on driveway camping for a bit to get the basics in order.
