Cool picture Herb. First RV in America?? LOL
Reminded me of this 'house car' from 2003 Ford Celebration
The "House Car" in the two pictures that Dan posted above belongs to Ed and Rose Organek from Portland, CT. That's Rose behind the car in the first picture and Ed behind the right rear fender in the second picture.
They have documentation that the Strong and Hale Lumber Company built 6 of these and this is the only one left.
