BF, my tent is also somewhat like the MH Trango Assault . I have seen Jim's TNF Mountain Tent and they are about the same size.

The fly doesn't seem to tie down as tight as it should, but the pole design (5) should hold up pretty well in a bad storm. I haven't had it out in really bad weather, so not sure. I think it if was tied down properly and totally closed up, it would be pretty stable.

My tent is fairly heavy, because it is a convertible, so there is the weight of the mesh panels and zippers. It is a clip design too, so there is a lot of hardware on it.

It also has a small door and vestibule in the back, plus three mesh interior pockets.
