I am looking to build my own 2 person tent. It will utilize 4 trekking poles as the only time I would use this tent is when my wife or a friend is with me. The floor dimensions are a little different than it shows in my google sketchup. They are 90x54. The vestibule would extend out 21 inches. With the flat slanted roof, I think it would shed rain, but would have a tough time withstanding any snow load. I am not an engineer and am not sure about wind worthiness, but guess better than some, worse than others. I was planning to add vents on the front and rear and bug mesh from top to bottom similar to a lunar duo.
I was fortunate enough to buy some sil 2nds from David at Oware (thanks) so I plan to get to it after making a stuff sack or two to get the hang of sewing sil. If it turns out reasonably, I will consider using a lighter material.
What are your thoughts?
