Oh boy. Before using this tent this past weekend, I was coming from 2 person backpacking tents, single wall tarp shelters, etc. Let me just say, this guy is HUGE!! Four people would fit comfortably, with all of their stuff.
Setup: When I first saw the old school "poles in the sleeve" design, I have to admit I was skeptical. Cue memories of camping with my family, struggling to get the poles through the sleeve. Pole falling apart, poking holes in the tent body, etc. I have to say Marmot nailed it with this aspect. The poles are magnetized so there is no popping out or bumbling, and the sleeve material is reinforced and coated with a slick (pvc coating maybe" coat that helps the poles slide right through. Set up took 3 minutes tops with 2 people.
Tent: SO MUCH ROOM! Cant say it enough. Plenty of room for me and my girlfriend to sleep on our luxury Thermarest car camp pads, and for our dog to have her own pop up crate / bed, plus all of our crap. I am 6'5, and there was enough height in the middle for me to stand up hunched over (good enough to put pants on). The other great part is while this tent is by no means a backpacking tent, it only weighs 12lbs, and doesn't take up too much space in the car. No, this isn't as big of a concern with car camping. However, my car tends to get filled up with bike stuff, climbing stuff, etc, and so I want the essential "stuff" to take up as little room as possible, while still being comfy.
Durability: Can't speak to this as I only had the one weekend out so far. However all the materials seem solid and burly, and I have had the marmot firefly 2p (discontinued) for going on 7 years now with only one rip in the fly that was 100% my fault.
Long story short is that I would 10 / 10 recommend for your car camping adventures.
