I wouldnt buy a tent without seeing how good the canvas really really is in person. no matter what the ad says.
That one packs up large if its like oztent, you will need a roofrack. and then to get it off the roofrack...
if its just you and 1 kid, get a 9x9 single pole canvas tent from Rays similar to this...

Had mine 9 years, never leaked, and piss easy to pack and put up.
Or a Blackwolf.. They are awesome quick to put up (it may not look fast, but 4 pegs, and push the springloaded center up and your in), packing can be a challenge until you have it down. But still... I love mine

YMMV
PS... look at youtube for how easy blackwolf etc are.
