Key facts
- The 12V compressor fridge other fridges are measured against — 45L is the sweet spot for two people
- Rides inside the vehicle, not on the roof — fridge weight never touches your roof rating
- App-monitored temps and low-voltage battery protection are genuinely useful, not gimmicks
Fitment: rides inside, not on the roof
A 12V fridge lives in the cargo area or on a slide — its 42 lbs never touches your roof rating. The fitment questions are interior: does it fit your cargo footprint with the lid able to open, and can your battery setup feed a compressor overnight? Neither involves the load checker, which is exactly why fridge money is the easiest money in an overland build.
