We copied each rating from the seller’s listing as the brand states it; data date 9 November 2026.
Capacity and size
Capacity is the widest gap. The RecPro 6.3 lists 6.3 cubic feet and the RecPro 3.3 lists 3.3 cubic feet, both built for a fixed spot in an RV kitchen. The Frigidaire pair lists 4 liters, enough for six 12 oz cans, with a compact interior. Size follows the same split: the RecPro 3.3 is listed at 19.8 by 17.5 by 19.5 inches and the RecPro 6.3 at 25.0 by 23.25 by 53.5 inches, while the Frigidaire pair is listed at 10 by 7 by 10.5 inches in the bullets.
Power
Power is where the two sides part ways. The RecPro 3.3 runs on 12V only, while the RecPro 6.3 lists three power options, 110V-120V, 12V and propane gas, with gas-absorption cooling that runs on propane. The Frigidaire pair runs on AC or DC, and both listings include a car charger in the box, so they plug into a home outlet or a vehicle DC cigarette lighter outlet. The RecPro 6.3 is the only listing here that states propane power, and the Frigidaire pair are the only listings here that state a car charger in the box.
Weight and moving it
Weight decides whether a fridge moves with you or stays put. The Frigidaire pair are listed at 3 pounds each, with a carrying handle, so they move between a car, an office and a dorm. The RecPro 3.3 is listed at 52.0 pounds, which suits a fixed install with adjustable shelves and a reversible door. The RecPro 6.3 states no weight at all, which leaves its install weight unclear.
What the listings leave unclear
Several figures do not line up inside their own listings. The Frigidaire pink title gives 11.8 by 7.1 by 10.1 inches, the bullets give 10 by 7 by 10.5 inches, and the spec table gives 7.0 by 10.0 by 10.5 inches. The green Frigidaire has the same split between its bullets and its spec table. The RecPro 6.3 gives its length as 25.0 inches in the product dimensions and 24.75 inches in the size line. The RecPro 3.3 carries the part number RP-RFG-17-SS, which reads like the 1.7 cubic foot size, while its title and spec table state 3.3 cubic feet. Both Frigidaire listings carry the part number EFMIS229 against the model EFMIS171. None of the four listings states a safety certification.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For fridges, safety means a stated protection or certification, and none of the four listings states one, so the safety line is empty across the group. Three of the four listings state a warranty term: the RecPro 3.3 states 1 Year Manufacturer and the Frigidaire pair state 180 days, while the RecPro 6.3 states none. How we pick explains the weights.

| RecPro 3.3 Cu Ft 12V RV Fridge | 9.5 | 30 | 21 | 20 | 0 | 3 |

We place weighted points on a scale whose ends are 9.2 and 9.8. Because the mapping is straight, a unit with more points never shows less.
RV fridge vs portable fridge: which should you choose?
Capacity and space
Start with the space you have and the load you carry. The RecPro 6.3 lists 6.3 cubic feet for a full RV kitchen load, and the RecPro 3.3 lists 3.3 cubic feet with a built-in freezer. The Frigidaire pair list 4 liters for six 12 oz cans, which suits a lunch and a few drinks rather than a full shop.
Power on the road
Match the fridge to the power you have. The RecPro 6.3 lists 110V-120V, 12V and propane gas, so it keeps running away from a plug. The RecPro 3.3 runs on 12V. The Frigidaire pair run on AC or DC with a car charger in the box, and the thermoelectric design is worth a closer look in the compressor vs thermoelectric 12v fridge comparison. For the propane side, see 12V refrigerator vs propane refrigerator.
Weight and moving it
If the fridge has to move, weight rules. The Frigidaire pair are listed at 3 pounds with a carrying handle, while the RecPro 3.3 is listed at 52.0 pounds for a fixed install. The RecPro 6.3 states no weight, so check the listing again before planning the install.
| If you need | Look at |

- Match capacity to the load: 6.3 or 3.3 cubic feet on the RV side, and 4 liters holding six 12 oz cans on the portable side.
