No Idea. Probably similar construction to skampers, palominos, jaycos, etc of that era. If you are looking at that old of a camper you are most likely on a tight budget as I was. Main thing to look for in the old campers is water damage and the canvas condtion. Sometimes you find an old gem that will work fine for you with some TLC. Plenty of us have done that.
Personally I have owned a 1989 Skamper which I brought back to life tinkering on in for the 3 years I owned it. It was one of the best $700 investments I've made. I took it all over and back and had some great trips and memories.
I then "traded" it in for a 1990 FWC Hawk for only 2 reasons, It fit my truck and had a bigger bed. I have since "restored" that one as well.
So to answer your question (is it worth looking at) you need to figure out what you want. If you are just looking to try the pop-up style camping out and the camper is in good condition, go for it. If you are looking for a camper to last you for a long time, save $$ and buy a newer camper which the company is still in business. Hope that helps. GOOD LUCK!
