I bought a 1973 bethany pop up camper.. Is it worth it?

I just bought a 1973 bethany pop up camper for 100 bucks! The interior is in great condition, the frame and outside is also in great condition, the only thing thats wrong with it is the canvas.. Its tore up and ripped on the wings... Is it worth buying a new canvas, or should i gut it and make it into a trailer? How much is a canvas for this trailer? Anything ideas or help would be awsome! I would love a camper but dont have alot of money to stick into one...
