The one side of our sink is large enough for a dishpan which we use all the time. Saves on scratches to the sink and it's more sanitary because it has soapy water in it all the time rather than using a sink that you're putting foodstuffs in or washing your hands. The other side is smaller but still works for quick rinsing. I don't tend to use big pots anymore and if I did, I'd use it as my dishpan. We also grill a lot. I really think washing dishes is good therapy. Having your hands swishing in calming warm water and it gives you quiet moments to think. :)
Since we dry camp a lot and need to conserve water I don't wash dishes after every meal. I have lots of silverware. Sometimes, depending on the cooking techniques I'll even wait two days or so to do dishes. Also, right after eating we wipe down all dishes and pots with a wet paper towel to get the majority of food off. We would never put all of that crud in our holding tank and also the dishes don't smell if they set a while and they're easier to clean. This especially holds true for greasy frypans - no grease goes in the holding tank - and no coffee grounds. The dishwater doesn't even look dirty when I'm finished. In addition, by using a dishpan, many times I'll dump the dishpan into the toilet or even put in in a container and use it for toilet flushing if we're running short on water. We always seem to fill the grey faster than the black tank and the black tank needs a lot of water anyway for proper dumping.
Freezer space: I buy large packages of meat but as soon as I get home I repackage into serving size portions. I can easily fit 25 dinner meals in the freezer along with bags of frozen veggies. I arrange the types of meat in different areas so I can open the freezer and just grab what I want without having to root around in the whole freezer. I also do lunchmeat by buying in quantity and freezing small packages along with sliced cheese for sandwiches. It freezes well. Then I just have to shop for dairy, bread or fresh veggies to fill in. I don't spend a lot of time grocery shopping. Again, since we dry camp a lot we wouldn't consider an extra freezer using electric.
We don't have a washer/dryer either. I prefer to get two weeks' worth done at once in 1-1/2 hours. I have better things to do than putzing with laundry daily.
It works for us!
