Red Guthrie and Dale Martfeld began RV manufacturing in a building previously used as a chicken house. The first Recreational Vehicle they built was a fold-down camping trailer. Later they added camper tops for pick ups followed by slide-in pickup campers. As camping in RV's increased in popularity they expanded and began building Travel Trailers, 5th Wheel Trailers, Chassis Mount Campers, Mini Motorhomes and finally full sized Class A Motorhomes. The business changed hands several times until Red Dale RVs were no longer produced!
Looks like they were built from the early 60s and into the 70s
