What did you use for a scale? This beam scale is all I have got, I have used it to weigh my stuff for years and consider it reliable. Each mark on the scale is 1/2 lb. It would be good to weigh in on a scale with finer calibrations. The stove is made from a 6" can. The bottom cover is older style maybe heavier with a stainless steel swing door instead of a slide door.
The 2-4 man shelter with the 8'x15'tan tarp I have shown on my posts weighs 5 1/2lbs.with the poles and pegs, it is a nylon canvas type material. What would silnylon weigh for that size?
