Chinooks are cool. So are the Chevy Blazer Chalets, which I think were made by the same company. The thing that stopped me from looking at any was I really wanted to be able to sleep 3 adults, and both the Chinook and the Chalet are really set up for two.
Besides the pop-up Chinooks they also made a sort of micro Class C with a full hard shell in (almost) stand-up height:
I looked at one of those, liked it, but ultimately decided the challenge of having a 1970s-era 4-cylinder pulling the weight of all that fiberglass, while dealing with California smog controls, was more than I wanted to cope with. Really distinctive, though, especially the split rear door.
