I have a eurika back country 2. Really a good tent. I am taking it on my 6 day in Michigan. Here are the other must haves for me:

shower shoes
ear plugs
ibuprofen (or tylenol pm ..zzzzzz!)
I am also bringing icy hot. Sure it smells but ohhh the relief!

I got my self inflating mattress from cabela's. It's sort of heavy, but well worth it. It blows up to about 1.5 inches and has foam in it.
