Thanks all!
As far as difficulty goes it was a bit tough to get all the panels to line up correctly so I would not recommend this type of tent until you have a few projects under your belt.
Matt, The dimensions were (not including beak length):
front = 48" wide and 36" tall
rear = 24" wide and 18" tall
the top portion (or roof/gray panels) was designed to hang 4" above so the roof portion is really 32" tall in front and 14" tall in rear.
The length was supposed to be 7' but somehow I lost a few inches and it is closer to 6'10". My initial tests indicate that this is still a fine length for me (5'10" tall guy).
The dimensions were designed to be the smallest I thought possible for me. I believe the beaks add significant protection for little weight. Without beaks the tarp would need to be longer.
As far as how I came up with these dimensions…I started with dimensions from Vick's book and ask how much smaller could I go. To figure this out I reviewed many cottage sites and looked at dimensions being used. For example I studied MLD's Serenity shelter as well as shelters on Six Moon Designs and Tarptent's websites. My thanks to those guys for publishing dimensions.
