Oddly enough, we went the opposite direction of simplifying. We ended up getting a large camp trailer and kept everything (and the kitchen sink) in there
. This made it so I hitched up and we left. We bought some food on our way so we didn't even have to plan that. We were camping atleast a couple times a month, all year long. It made it extremely simple to get out for a weekend even with our (at the time) 1-2 year old. It also made it so my wife enjoyed camping. Before the trailer, we got out once or twice a year was all and it was all my wife could do to tolerate it.
I love the idea of simplifying but it would have never worked for our family.
