Another reason I don't want to really attempt a DIY is the cost, I don't see myself using something I made, I would rather spend a little extra and get a whole new level of quality, plus it is real cold up here in Canada so there is very little real warm camping time. I don't mind the cold (cold on hot nights is a plus for me since I sleep hot) but I was thinking the HH with super shelter would extend my season more than some shifty homemade thing I attempted.
I think I will rent the Expedition, try it then shell out my savings for the Explorer if I like it.
Thanks for your feedback. Sorry for getting off topic.
