We have used many types of storage containers to keep and store foods on long trips. Rubbermaid as well as dollar store closable and sealable containers. We also have a great deal of cupboard space in our MH. A few years back it had become apparent that some and sometimes a lot of the food we carried was just in case type foods and we ended up bringing much of it back with us. We find we are more spontaneous on the road. Now we just pack enough for about a week at a time in the meal type items. We stop along the way at large grocery stores especially Kroger as that is where we shop at home. We stock up for the week to 10 days and then go on. That has worked better for us and allows more space for other items in the coach.
