Okay, so I bought an unidentified used Hennessy without a tarp. It is a classic bottom entry and lighter fabric than my Expedition. I think it is an Ultralight Backpacker model, but after getting into the specs, I see the Scout is the same dimensions (that is a puzzle too). Without having one to compare side-by-side, is there any way to tell one from another? The one I have is the coyote brown color.
