Downsize your kitchen utensils. If it is just the 2 of you, you only need 2 spoons, 2 forks, 2 knives. Bring along a set of plastic cutlery of 5 or 7 in a small box that can be tucked away for unexpected guests. Plates? You only need 2 plates. Get some paper plates for extra unexpected guests and just keep them tucked away elsewhere. Same for cups and coffee cups. Pots and pans? Most pots can be used as skillets. Most skillets can be used as a pot! Prep tools? a couple flat griddle flippers, a dipping spoon, a dipping spoon with holes for draining, a potato peeler, and a good set of knives. (we don't skimp on the knives. My wife got a butcher block set that cost about $300. One of those knives is better than ALL the knives put together in our house. This set stays in the camper, never leaves). Really, more than that you REALLY don't need.
We do have a wine bottle cork screw and a hand can opener.
By the way, our primary cooking pot has a lid. The lid has a bunch of holes in it. Perfect for draining water (like spaghetti) or anything for that matter.
If you REALLY go through your kitchen stuff, you will probably find you don't use some of those items. They can be eliminated right away. Look at each item and see if you can use it for multiple purposes. If you can, eliminate something else that duplicates the purpose. For example, a pair of meat scissors can also be used for cutting paper, string, rope, even small wire, fishing line and cloth. Why carry a dozen different kinds of scissors in your camper for each item, when one will do it all? Those individualized gadgets and utensils take up a lot of space, for no more than they get used for.
Downsize. If you've not used it in the last year, toss it out! Of course, if you have only 2 spoons, you do have to wash it immediately when done. You may want use it again to dig worms out of the ground for fishing next! :)
