I want to thank you for the review, and for the updates.
I'm fine with making small changes to make the mattress work. But the one question I have that you didn't seem to really address is how you at 5-9 can stretch out in it (I'm a short 5-9). You said that occasionally you hit the shell when rolling over. Is that the only time you notice the length? How often is sometimes (I know that's subjective)? When you do hit the roof, is it noticeable enough to be a bother?
Another question. You have any issues with inside temps when it's hot and sunny out?
Any other thoughts, observations, etc?
CVT has a group buy going on (on expo portal) with a 30% discount, and are willing to give a raincheck option for those wanting a hardshell tent (production is getting moved to the US, with a May 2014 timeline). I've been going back and forth between this and a James Baroud Espace Evolution (same idea as the Mt Baker, but the front pops up 18"). However it'll likely be $1000-1500 more than the price of the Mt Baker (with the discount) after shipping.
Reason I ask, is this is purchase that I only want to make once... I'd be okay with the ~$3500 pricetag of the JB... as I feel it'll meet all of my needs without ANY issues. However the only real concern I have with the CVT (or even the Autohome Columbus) was the length... so if that's not really going to be an issue - and from the sound of your experience it isn't, then I think this is the direction I'll go in.
One question you had asked re the bottom/top rollup doors... Having had a RTT with the top roll up doors... My complaint with them was that I couldn't drop the door and still have privacy inside and be able to have the screen open to get the breeze. Where as if you have a door that rolls up from the bottom, you can close the door, but leave the top half open so that you can still get the breeze, but no one can see in. Might not be an issue when on the top of a vehicle, but as my RTT is on my trailer, it's only ~4/5' off the ground.
