The Clam 1660 (green) is on sale for $220. W/free shipping from L&M supply. If also you want side panels it is best to call them and they will ship them with your tent for free shipping on the panels. (The shelter is 6" long when folded up.)

What are the dimensions folded and bagged?
I don't have access to my clam now but it is 6 ft long, it just fits in my pick up bed. It fits into a bag maybe 10"x10" x 6'. The bag is zippered from end to end. Just lay your bag down, unzip and start unfolding your tent. Same with folding up your tent. You can lag the bag on the ground and fold up the tent on top of it and zip it up. The bag has a long carrying strap.
The green Clam is more of a screen room with wind panels. The tan Clam has better wind panels and a lip on top to keep rain out better.
