1972 Ford RV - Can't find any info

At nearly 50 years since it rolled off the production line and considering the over condition based on the listing, any literature you do find will be of little use. If you do choose to attempt to recover and restore the coach you'll be starting from scratch as there doesn't appear to be much in the way of anything that would be reusable. Very little of the house side looks recoverable and no telling what the frame looks like without climbing under it to inspect. Strong possibility the engine is frozen and the transmission is long past it's use by date.

Best to allow the environment of the Colorado prairie to continue it's work converting the rig into more stable elements of iron and aluminum oxide along with broken long chain hydrogen-carbon elements.
