Homebuilt A Liner?

Hi guys,
I like the size and weight of the teardrops, but I want to be able to stand up in my trailer. Pop ups are nice, but I camp in COLD weather (0-20f) and I'd really like hard insulated walls, with a small heater. I've been combing the internet looking for folks who have built their own A-Frame trailer similar to the ALiners, but with ZERO luck.
Has anyone built their own A-Frame style pop up camper? Know anyone who has? Thanks!
