Quick and to the point. Nicely done. I like the tip on sitting down and using your foot for leverage to get the final tensioning bar in place. You are the first person I've seen on RU-vid do that.
Hi! You must have to be a linebacker to get the top metal over the end tabs on the tension bar. Definitely NOT for a slightly built person. Do I sound frustrated?
Don't think your wife or kids are going to be able to assemble this - you need to apply massive force to get the tension rods installed and as you do that, the cot will attempt to swing away in the opposite direction, so you need to sit on the ground with both feet up against the end and side to hold it in place.
