I have a single. I do like it. A little on the small side. Overall it makes a quick and simple camp. One thing I would suggest with the double is make sure it fits in your vehicle. I spent the whole archery season in mine with few complaints. I will list some down sides but, overall I like mine a lot and find it very useful. I do wish I bought the double but, I drive a jeep and it would not fit inside. I often just leave my bag inside when going from one camp to another.
The padding sucks so get a good mattress or sleeping pad.
I am short and it is a little on the low side for me. Suggest a tarp or something when using in inclement weather.
It is simple to set up but, at times it can be a little frustrating. Practice at home unless you want to give some people a good laugh.
It can be a little unnerving when you have a bear sniffing around the outside. Some of my hunting buddies call it the twinky shack. Something about a bear being able to get at the soft filling very easy.
If you and your wife like to make a quick simple camp I say go for it. It is much more comfortable than the ground.
