Here is a link to what is included in this system:
Its an all in one unit. The Tarp is built in along with bug netting windows. The top half can come off if you want it to but then there will be not bug netting windows. You can order the bug netting from Helsdon Outdoors if you want the official one or you can make your own with bug netting http://helsdonoutdoors.com/allproducts.aspx
You can see a video of it here - http://www.youtube.com/watch?v=9DaTc8kLa4I
And here - just make sure you attach the tie downs unlike this silly guy did LOL - http://www.youtube.com/watch?v=AUZpsOIyh7E&feature=fvwrel
This is exactly what you would be getting, except the Jungle netting.
