I just got an email from C6 (amazing how when you look at something on-line, you suddenly start getting emails and such from them).
Anyways... for Christmas they're having free shipping on everything if I read it right. Use the code
SANTADELIVERS at checkout. I don't know how long the offer lasts.
If someone was looking for a similar concept to the C6 for camping
and wasn't planning on putting it on their roof, consider a double sized tent-cot. Here are some ideas:

You don't get the foam mattress (I use a self-inflating 3" thick sleeping bag air mattress), but you are off the ground. Easy set-up. Removable rain fly. And they fold up. Weight figure around 50lbs.
But priced less than half the cost of the C6. Footprint is about the same (48" [or a little wider] x generally 84").
My buddy and I used a pair of Cabela's double-cots for a trip we took up into northern Canada (using them on the ground). After the trip, he took one back home, and I kept one. I ended up mounting it on top of my lil' trailer to use as a RTT as an experiment (outer legs removed since they'd just be hanging in the wind). I had to have a cover made for it (the factory cover would no longer work since the legs were now extended). Cover was a little over $400 (very well made and thought-out though by a place that did that sort of thing). So between the cost of the tent-cot and the cover, I could have (at the time) bought an entry-level RTT. But I've been happy with it. It weighs about 50lbs - most RTTs start in over 100lbs.

This picture below makes it look like the floor isn't flat. It is flat; there's just an additional piece of tent fabric under the floor that makes it look that way.

Yup - I can still get into the trailer even with the tent-cot opened up.
