Do you know what brand/model this bed camper is?

That's still very helpful, thank you! I know nothing about campers, I just have construction/electrician experience and am taking a stab at something new. Plus I think it will be a great addition to my spring trout fishing trips. But I just did a quick search on Gen-L Truck Caps, and the construction on the frame looks extremely similar so thank you!
