Thanks Tarzanman...I know about the tarp thing & that there's some prep work involved to waterproof etc. - and that to eliminate some of the frustration ON SITE we need to know how to set the thing up...I just don't know how to pick out the darned tent so I can make a purchase I don't regret! And this IS a purchase that may only be used once a year - so the higher end Paha Que, Kelty & North Face tents are OUT! I read some discouraging things about the Ozark Trail & Eddie Bauer tents so have eliminated those - which leaves basically leaves Coleman as our main contender...
I know we're only 3 ppl but I want a larger tent 'cuz I want room for STUFF & I want to be able to stand up inside! (We have a little 3 pp 8x8 Ozark Trail that we bought a few yrs ago for DS to play with in the yard - but the air mattress FILLS it!)
Anyway, this is the one that I WANTED to find but can't find it in a store locally, only online:

And this is the one that I actually BOUGHT (the bag says the seams on the rainfly are taped) but that I'm worried will be hard to put up (but I could always return it & order the other one...):

Do you think it really matters & that since they're lower end I'm gonna get bit in the butt either way?! I printed out all of the reviews I could find & DH couldn't care less....and I'm back to why I have the screen name that I do!

Obsess, obsess, obsess!!
THANKS!
