Cargo Trailer - Most efficient in family camping

I've tried all methods of family camping. From small tents, to large canvas tents, to ground pads, to cots, to car camping, to fifth wheel trailers. All of which are a lot of work when your out in the mountains a lot, and are generally a pain in the ass though repetition. It has been a mission to make it more efficient, and less of a PITA. So finally, this I think, represents the least amount of work, most efficient in setup and take down, and requires zero maintenance. If you can dig hole for a pop up outhouse, and your family doesn't mind roughing it just a little bit; this, I think, finally, after much trial and error, is the way to go. At least for us.
