I've seen Rayzr at Walmart parking lot.
Very nice elderly owner was using it for between the hotels stays while pulling his glider all over the country.
I learned that lot of airports will arrange small airplane to pull your glider for really small amount.
Coming to camper, you can have almost the same in any SUV once you fold rear seats.
As Rayzr management says - the idea come from semitruck sleeper.
Truckers have showers at each truck stop for free.
Usually such shower is 3 times bigger than the camper.
In case you wonder why truckers stay 2 hr in the shower...
