Any Help?

Not sure if this is the place for this But I am needing some help identifying the camper I just picked up last week. I believe it is made by Play-mor (only for the decal on the side) with a base size of approximately 77"x96". Looks to be 70s ish but I could be totally wrong. The Door opens to the back. Use to be on an axle but purchased without. I bought it planning on attaching it to the front of my trailer as seen in the pic for use as a crawler hauler. I'm really just trying to find out more about it. It is just a shell and has been gutted. I have my own ideas on how I am going to set up the floor plan but was hoping that with some more info I could possibly find a picture or two of the original interior to help me out. If not could anyone one steer me in the right direction. Kinda new to the whole camper thing.
