Plenty of van and car campers keep food cold with a passive cooler instead of a 12V fridge, or alongside one. A good cooler needs no battery, no wiring and no ventilation gap, and it costs considerably less than a fridge and the power system to run it. The trade-off is ice: you restock it every few days, most of the box is ice if you pack it properly, and the food inside only stays safe while the ice lasts.
Size the cooler to your trip length and your floor space, not to the number on the label. Most makers recommend about twice as much ice as contents, so roughly a third of the interior holds food. Hard coolers with up to three inches of insulation hold ice longest; soft coolers are lighter and easier to carry but hold ice for less time. Check the exterior dimensions and the height with the lid open against your van or cargo area, and work out the weight full with ice: for a hard cooler that is often two to three times the empty weight or more. If you camp in grizzly country, look for an IGBC bear-resistant certification and note any padlock condition. Treat ice-retention claims as best cases under the maker's stated conditions.
We don't run our own ice-retention tests. We compare manufacturer dimensions, interior space, empty weight, ice capacity, insulation, latches, drains and certifications, read each maker's ice-retention claim alongside the conditions it states, and use owner reports to check how coolers hold up in vehicles.
A cooler suits weekends, car camping and builds without a house battery. A 12V compressor fridge suits trips longer than a few days and full-time travel, because the whole interior holds food and there's no ice to buy, but it needs a house battery and charging.
Hard coolers have thicker insulation, a drain and, on some models, bear certification, so they last longer between ice runs. Soft coolers weigh a fraction as much, carry on a shoulder and fit odd gaps. Many campers use a hard cooler for food and a soft one for drinks.
At the usual 2:1 ice ratio, a 35-to-45-quart cooler holds a long weekend of food for two. A 50-quart-plus cooler holds more ice, lasts longer and suits longer gaps between towns, but it is bigger outside and heavier full.

For: Most space per pound
An injection-molded hard cooler that RTIC says is more than 30% lighter than rotomolded coolers of the same size: 76 cans or 51 lb of ice at 21 lb empty, with an up-to-7-days ice claim under RTIC's published cooling tips. It's a bigger box outside, has no bear certification listed, and the basket is sold separately.
For: Bear country weekend trips
A rotomolded hard cooler with up to 3 inches of polyurethane, rubber T-latches and IGBC bear-resistant approval when locked with padlocks, in a footprint close to a 35-liter 12V fridge. YETI publishes no ice-retention days figure, and at the recommended 2:1 ice ratio the listing says it holds 26 cans' worth of contents.
For: Compact bear-certified cooler
A compact, narrow rotomolded cooler with 2 inches of insulation, silicone gaskets, stainless-hardware draw latches, IGBC bear-resistant certification and a 10-year warranty listed. It suits one or two people on weekend trips; Engel's up-to-10-days ice claim has no stated conditions, and Amazon stock is limited.
For: Carry-out and drinks cooler
A 6.8 lb soft tote cooler with a welded leakproof liner, magnetic closure plus buckles, and room for 42 cans or 32 lb of ice. It fits gaps a hard cooler can't and works well as a drinks cooler beside a fridge, but YETI publishes no ice-retention figure, it has no drain, and it isn't dry-ice compatible.
