loading and unloading supplies

My goal is to take as little as possible, while the wife's goal is the opposite. And, she likes to use the trailer as a shed between trips. Extra tents, sleeping bags, chairs. Stuff we only use on big family trips finds it's way into the trailer. So we are continually loading and unloading. Or, should I say, she is continually loading, and I am continually unloading.
The trailer does have it's own set of stuff. We only have to pack non-canned food and clothes. Towels and such get washed and put back in the trailer. It's much easier now the kids are gone.
