I love mine. I would add grommets to the bottom of the annex flaps so I can use them as a mini awning. I talked to Bobby about that and apparently that is something they are going to implement in future versions. I also want to do a stove jack in the annex to use a Seekoutside titanium stove during hunting season and winter camping. I have changed my foam mattress out to a custom one that is 4" thick with microcoil pockets. Long term, I'll store the mattress inside. I'll always air the tent out and let it dry out if I had to put away damp or wet coming back from a trip.
Here's a link to the mattress. It's extremely comfortable
