Dometic RM2354RB1F 3 cu ft 3-Way RV Refrigerator/Freezer

The Dometic RM2354RB1F (Dometic part 9105306317, model RM2354RB1F) is the 3-cubic-foot 3-way RV refrigerator-freezer in the Dometic compact-RV refrigerator line. The standout feature in this model: 3-way power (12V DC, 120V AC, OR LP gas), which means the fridge can run on whichever power source is available without needing to switch to a different appliance. Smaller-format than the typical 8 cubic foot Norcold-class RV fridge, but still has both refrigerator and freezer compartments inside the single door, plus eye-level top controls and automatic temperature regulation.

What 3-way power means. Most absorption RV refrigerators are 2-way (AC + LP gas) or 1-way (LP gas only). The 3-way design adds 12V DC operation as a third fuel option. When you're driving down the road with the engine running, the truck or RV's alternator powers the fridge directly through the 12V circuit. When you stop at a campsite with shore power, the fridge switches to 120V AC. When you're boondocking off-grid without shore power and the engine is off, the fridge runs on LP gas. The result: continuous refrigeration on every leg of the trip without you having to think about it. Especially valuable for truck campers and travel trailers that get unhooked from the tow vehicle at the campsite (no engine running, no shore power), where the 12V option keeps the fridge running on the trailer's house battery for short stops.

3 cubic foot capacity. 3 cubic feet is the right capacity for compact RVs, smaller travel trailers, truck campers, pop-up campers, and boat installs where galley space is limited. Room for a few days of fresh produce, drinks, and basic groceries for 1-2 people, or a long weekend's worth of perishables. For larger RVs that need to feed a family for weeks at a time, the 8 cubic foot Dometic and Norcold options are the right capacity. For compact installs where every cubic foot of cabinet space matters, the 3 cubic foot RM2354RB1F is the sweet spot.

Single-compartment with built-in freezer. The 3 cubic foot total interior is divided between the main refrigerator section and a small built-in freezer section, both behind the single door. Freezer is sufficient for a few days of frozen meat, ice cubes, frozen vegetables, and similar small items. For larger frozen storage or for ice-maker capability, step up to a 2-door model with a separate dedicated freezer compartment.

Top eye-level controls with automatic temperature. The control panel sits at the top of the unit (above the door) where the user accesses it without bending. The temperature control is automatic - set the desired temperature and the unit maintains it without further adjustment, regardless of ambient temperature changes. The auto-control adjusts the cooling cycle as needed to hold the setpoint, which keeps food at consistent safe temperatures even when the RV or boat sees significant interior temperature swings between hot afternoons and cool nights.

Stainless steel exterior with black frame. The exterior surfaces are stainless steel for the modern appliance look that fits typical RV and boat galley cabinetry. The frame around the door is black, providing visual contrast against the stainless and matching the typical black accents in modern RV / boat galley trim. The combined look is meaningfully more upscale than the basic white plastic exterior of older RV refrigerators.

1/2-gallon container shelf storage. The interior shelves are sized to accommodate 1/2-gallon containers (the standard size for milk jugs, juice cartons, large beverage bottles). Older compact RV fridges often had shallow shelves that wouldn't fit a half-gallon jug standing up - meaning you'd have to lay the jug on its side and risk leaks. The RM2354RB1F's deeper shelf design fits the typical large container without issue.

Why absorption refrigeration in an RV / boat. Absorption refrigerators (the technology in the Dometic RV fridge line) use a small heat source (LP gas flame, AC heating element, or DC heating element depending on which fuel is selected) to drive the refrigeration cycle. No compressor, no moving parts in the cooling loop, no continuous high-current electrical draw. The trade-off is slower cooling than compressor refrigerators, but the benefit is dramatically lower power draw on 12V DC and the ability to run on LP gas with essentially zero electrical draw. For the RV / boat use case where battery capacity is precious and shore power isn't always available, absorption refrigeration is the right technology.

Compact dimensions. 30-3/8 inches tall x 21-11/16 inches wide x 22-1/16 inches deep. Designed to fit standard RV refrigerator cabinet cutouts in the compact-fridge size class. For built-in installs, plan the cabinet cutout slightly larger than the external dimensions to allow for ventilation clearance and the trim ring. For portable installs (where allowed by the RV's design), the unit can sit on a counter or floor location with the appropriate ventilation around it.

71 lb weight. The unit weighs 71 lb empty. Account for that weight in your install planning - the cabinet shelf or floor location must support the loaded weight (which adds another 20-30 lb of contents in normal use).

Power consumption. 1.45 amps at 120V AC (about 175 watts), or 14.5 amps at 12V DC. The 14.5 amp DC draw is significant - on 12V DC, the fridge will discharge a typical group 24 RV battery in about 6-8 hours of continuous operation. So the 12V mode is intended for short periods (a couple hours of driving with the engine running and the alternator charging) or for use with sufficient battery / solar capacity to sustain the draw. For extended off-grid stays, switch to LP gas where the electrical draw drops to near-zero.

Installation. Install in a cabinet cutout sized per the install instructions. Connect 120 V AC supply wiring through the appropriate fuse or breaker. Connect the LP gas supply through a flare fitting from the RV's existing LP distribution. Connect the 12V DC supply from the RV's house battery through an appropriate inline fuse. Connect the rear vent to the exterior of the RV (RV refrigerators reject significant heat through the rear coils that needs ventilation to ambient). Level the unit at install (absorption refrigeration requires reasonable level for the refrigerant flow to work correctly).

What's in the box. The RM2354RB1F refrigerator-freezer unit (with all factory-installed internal components), the install instructions, and the operating manual. Required separately: 120 V AC supply wiring with appropriate fuse, LP gas supply line and shutoff, 12 V DC supply wiring with appropriate fuse, exterior vent fittings if not already installed in the RV.

2-year limited Dometic warranty. Same-day shipping before 3 PM ET on in-stock units. Note: oversize shipping carton (71 lb in a 23 x 25 x 34 inch box) may incur freight surcharges from the carrier on certain routes.
