Thank you all so much for your help! These answers are a great start. I think my husband may for the "new gizmo" approach. He also seems to like new tools. I have never seen him do anything with them, but at least we'll have them!

I also like the camping idea. We already have a tent and sleeping bags that we have used with our son. Would this be for sleeping in the backyard in hot weather if we stay put, or just for use when "bugging out"?

I am going to try out different combinations of words while using the search function. I am sure I will find the threads you referenced.

Thanks again!
