Great tent. With a bit more headroom and larger or second vestibule area and a window or two, I'd give it 5 stars indeed. Ok so it's designed for weather resistance, I've not had it in a rain storm yet. I like camping according to weather locally.
Two people comfortably on one inflatable mattress, 3 maybe on individual quarters, one more and I'd have to stay in the car, I'm average build. We use a Queen sized 2 pc airbed
in here and have just enough room on either side and at foot of bed to maneuver.
An absolute cinch to pitch or strike. Like a dream. Lightweight enough for me for a short backpack trip (only one strap on cover bag though).
This tent took the place of a returned Kelty Mantra7, and I am fully satisfied with it.
I would like to see out though when animals come snorting and stampeding by at 2am and stop nearby...somewhere, oh and what exactly were they running FROM? Search me, a good rain fly seems not to include a visual ability, rather to keep you from the elements. No problems with the fly and ventilation. This Casa 6 breathes very well, so in temps below 50's, better have a warm bag to sleep in. Cleans easily and sweeps out just fine when you hold the tub floor down a tad. Zippers, so far so good.
All in all, you have 2 poles serving 6 purposes with the 3 way hubs. You place tent, put shock corded poles in place as a frame, you clip tent to frame, place fly when time comes using same frame pole ends. Remove pole end from grommet and place fly grommet over end and tent grommet and return to ground or fly grommets. So simple it's a dream to set up.
