The overhead cabinet in our 25 foot Class C is about the size of a carry-on suitcase, and it is the only overhead space I have for food storage. For the first few years I kept a stack of rigid plastic containers up there. Every time we crossed a rough bridge on Highway 101, I would open that door and find them scattered like dice across the shelf. In spring of 2025, Ray and I bought the Annaklin 8 pack collapsible silicone containers at the same time as a new cookware set. We bought them because they folded flat, which is not a glamorous reason to buy anything. Eighteen months later, I would buy the same eight pieces again without thinking about it.
What follows is the plain list of why they earn their shelf space in a small rig, in the order it actually matters when you are standing in a galley with two feet of counter and a water tank you have to conserve.
The eight pieces that fold down instead of spreading out
Four sizes, snap lids, and a cabinet shelf that stays closed on a rough road. Ours have been in daily use since spring 2025.

A full container stands at its full height. Push it down and it folds in on itself, and all eight end up in a shallow pile. The listing says the fold saves up to 50% of the space, and in a cabinet this size that is the difference between the shelf holding food storage or holding nothing at all. On travel day, when the fridge is empty and everything is washed, all eight fold down and the shelf is free for the coffee can and the cereal box. That is the reason we bought them and it is still the reason we keep them.
Four sizes cover everything from half an onion to a pot of chili
The set runs 11.8, 16.9, 27 and 40.5 ounces, and that spread is what makes it useful rather than decorative. The little ones take a cut lemon, a spoon of leftover rice, the last of the grated cheese. The 27 ounce size is my everyday one for a portion of soup or a salad for lunch. The 40.5 ounce size holds what is left of a pot of chili, which in our rig means two more meals. Altogether the eight pieces come to 192.4 fluid ounces, roughly what the two of us eat over three days.
One container goes from the freezer to the microwave to the table
This is the part that saves the most work in a small kitchen. I freeze the second half of a batch of stew on Sunday, thaw and reheat it on Wednesday, and we eat out of the same container with a plate underneath it. The listed temperature range is -4F to 428F, so the freezer and the microwave are both inside the range it was built for. In a galley where the sink is also the counter, not washing a separate reheating dish is a real saving.
Four snap buckles keep the lid on over a rough road
The Annaklin lids close with four snap buckles and a silicone seal ring, and that is why I stopped finding soup on the cabinet floor. I will be honest with you about one thing: the lids need a firm press all the way round, and if you stop halfway the buckles will not catch. Ray learned that the hard way with a container of chicken soup. Do the press properly and the lid stays put through a mountain pass. Skip it and you will be wiping down a shelf.
Washing up takes a small amount of water instead of a sinkful
Water is the thing I ration most carefully, so this matters more than it would at home. A quick wash with a little hot water and a drop of soap does the job on the silicone, because food does not stick to it the way it sticks to a scratched plastic tub. The set is listed as dishwasher safe, and when we are back at the house in Salem I run them through the machine to reset everything. On the road they are a two minute hand wash and back in the cabinet.
They pack flat in the outside bay for picnic table lunches
Before we head down to the lake, I make sandwiches and cut fruit into the smaller sizes, snap the lids, and stack them in a canvas tote in the outside storage bay. Because the walls fold, the empty ones ride along at almost no thickness, which means I can carry extra containers for leftovers without giving up the space a rigid set would take. We have brought back more than one stranger's leftover cornbread that way. It is a small thing that makes a day out easier.
Nothing rattles in the cabinet while we drive
Rigid plastic containers in a moving motorhome talk to each other. Every bump brings a clatter that makes you think something has broken. The silicone ones land soft and stay quiet, so the cabinet is silent from the moment we pull out until we park. I did not expect to care about this and now it is one of the reasons I would not go back. A quiet rig is a rig you can sleep in at a rest stop without being woken by your own dishes.
They are BPA free, so reheating leftovers does not make me think twice
The Annaklin containers are listed as BPA free, and the lids are plastic while the bodies are silicone. I am 67 and I have reheated food in a lot of questionable containers over the years. It is a relief to have a set where I do not have to reason with myself about it at nine at night. That is not a dramatic benefit. It is just one less thing to wonder about in a kitchen where I already think hard about propane, water and weight.
They double as prep bowls, so there is less to wash at the end of the night
I chop an onion into the 27 ounce container, carry it to the two burner cooktop, and tip it straight into the pan. The same container holds the trimmed ends until I walk them to the trash. On a night when I am also grilling outside and Ray has the campfire going, that saves me a bowl, a trip and a wash. The silicone also means I am not scraping at the bottom of a bowl with a metal utensil, which is more than I can say for some things in my galley.
Eight pieces cover prep, storage and packing, so nothing else comes aboard
When they are not holding food, they are stacked flat and out of the way. When they are holding food, four sizes handle whatever the day produced. I no longer carry a separate set of prep bowls, a separate lunch box, or a loose collection of lids that fit nothing. One narrow drawer and one overhead cabinet is all the cookware storage this rig has, and the containers live entirely in the second one. That kind of tidiness is worth more in 25 feet than it is in a house.
What I'd Skip
Two honest cautions. First, I would skip packing anything tomato based into the Annaklin containers for days at a time. Chili and marinara leave a faint orange tint in the silicone that does not come out with a normal wash, and while it does not affect how the container works, it bothers me. Second, I would skip laying a full one on its side in a soft bag. The buckles hold well enough for a tote carried upright, but I am not confident enough to trust one sideways under a camp chair. Neither of those is a reason to leave the set at home. They are the reasons I pack it the way I do.
Eighteen months, a lot of rough highway, and not one lid has come off inside that cabinet.
If your cabinet is the size of a carry-on, this is the set that fits it
Eight pieces, four sizes, snap lids, and a fold that gives the shelf back when you need it. Ours have ridden from Oregon to Arizona and back.
