These come up from time to time. Usually attached to a blazer. I believe FWC used to make a "blazer model" for SUV's like the blazer, bronco and scout with a removable top.
I remember looking at those with my dad back in the '80s. We had a bronco and he really wanted one. Our neighbor at the time had a pop up for his 1st gen bronco.
I have a '76 Bronco with a FWC. My wife and I LOVE it! It's small enough to get into the back country and has everything we need. Retro camping is fun!
