That would definitely be useful info...it's gonna be quite a bit of work if you include all the models of all the manufacturers. But if you wanna put a chart together, we'll put it in the articles section...I'm sure everyone would appreciate it.
If you do that, please include links to pages where the info came from and a blurb about the options included in that weight. If you don't know html, just put it into Excel and we'll take care of the coding.
Ed Speer's Hammock Camping newsletters have a long list of all the camping hammock manufacturers he knows of...that would be a good place to start.
So are you volunteering?
