4wheel pop up campers are probably the most well known brand for the blazers. I think another one I've seen was a palomino, but don't remember who made those.
Keep this in mind, the four-wheel brand built their camper with metal framework. The palomino has wood framing. Wood is more prone to flex when off road.
I have seen a couple of early Phoenix brand blazer campers for sale here in Colorado too. Those early ones were wood too, but later they went with metal.
Google blazer camper and look at the images. You see a lot of chalets, but the four wheel camper will come up too.
