This has got me thinking,,,,,as dangerous as that is for me,,,,

I've started looking for a 3 room tent to do car camping with the entire family.

Setting that up in my garage would increase personal privacy a bit, and would make better use of 1 wall by using cots and/or inflatable mattresses inside of my garage shelter.
