A colleague of mine when I worked for a NASA contractor in Virginia, in 1971/73, had worked for Open Road. They were located in Florida someplace, maybe Sanford. From the stories he told about the way things were done, I'm not too surprised they went out of business.
There didn't seem to be much engineering effort. One story was that the first time they built a new model Class A on a GM chassis, they drove the rig down to the local Midas mufler shop when the body was installed and said "Put an exhaust system on this thing". Midas did, and they drove it back to the plant, took photos of the installation, then removed it. Using the photos and the first example on the bench, they made production drawings for future manufacturing.
On problem they had was convincing customers they really were "new", particularly customers in the western states. GM had contract drivers take the bare chassis from the plant in Detroit and drive them to Florida. Once the rig was built, OR people were given the job of driving them to the dealers. He took one to San Diego and it had almost 5000 miles on it before the customer ever saw it. I believe they started taking a new speedometer with them on the trip and replacing the original one at the dealer's shop.
