A sealed crate for the food that must not get wet.
Condensation in a van is relentless and it is the enemy of every dried thing you own. A sealed crate for flour, oats, pulses and spices is the difference between a cupboard that works all winter and one that develops a smell in November.
Look for a rubber gasket and clips rather than a push-fit lid. Clear ones let you find things without unpacking, which sounds trivial and is not.
Airtight food containers
Square, stackable, genuinely airtight.
Clip-top jars
Glass jars with a rubber gasket, for the things you reach for constantly.
Desiccant sachets
Not the same thing as an oxygen absorber, and used in the same place for a different reason.
Food-grade buckets
The container the gamma lids screw onto, and the base of any bulk store.
Fridge thermometer
The cheapest genuinely important thing on this page.
Gamma seal lids
Screw-top lids that convert a bucket into something you can open daily.
