Finding the best 22-inch over-the-range microwave for an RV takes a little flexibility: none of the models here is exactly 22 inches wide. The closest option is a 24-inch COSMO, while the other picks are roughly 30 inches wide. Before choosing, compare the microwave’s full dimensions with your cabinet opening and confirm that your RV’s electrical system, mounting setup, and venting arrangement can support it.
Below, you’ll find five over-the-range options, including one described as RV-friendly and one with convection cooking. Treat advertised RV suitability as a starting point—not a guarantee of fit in your particular vehicle.

Our Picks: Best 22 Inch Over The Range Microwave For Rv reviews
1. COSMO 24-Inch Stellar Collection: Closest Match to a Compact RV Kitchen
The COSMO is the most compact option in this group, with a listed width of 23.8 inches. That makes it a closer starting point for a narrow RV kitchen than the other models, though it is still wider than 22 inches. Measure the available opening carefully, including space needed for mounting and ventilation.
It combines a 1.34-cubic-foot interior with 1,000 watts of cooking power, 10 power levels, and a built-in vent fan. Touch presets handle common tasks, while sensor cooking can detect when food is done and stop the cycle. The package listing also names a glass tray, turntable ring, exhaust adapter, grease filters, and an installation kit.
The listing describes this model as RV-friendly, but its 120-volt electrical requirement and 57.3-pound weight still deserve attention in a recreational vehicle. Confirm that your RV’s power supply and cabinet structure are suitable, and check whether the included vent parts match your intended setup. Its 16.1-inch depth and 17-inch height may also be limiting in a tight installation.
Pros:
- Narrower than the other models in this comparison
- Sensor cooking and convenient touch presets
- Built-in vent fan with included grease filters
- RV-friendly positioning in the product listing
Cons:
- At 23.8 inches wide, it is not a true 22-inch model
- Its weight and electrical needs require an RV-specific fit check
Verdict: Choose the COSMO if you need the narrowest over-the-range option here and your RV can safely accommodate its dimensions, weight, and electrical requirements.
2. GE 30-Inch Over-the-Range Microwave: A Practical, Familiar Layout
This GE is a conventional over-the-range microwave and hood combination, with a 1.6-cubic-foot capacity and 1,000 watts of cooking power. Its exterior measures about 29.88 inches wide, so it is a better candidate for an RV with a full-size microwave opening than for a space close to 22 inches.
Everyday controls include one-touch express cooking, four convenience cook settings, a digital display, and 10 power levels. The 300-CFM, two-speed fan helps move cooking odors, steam, and smoke, while a replaceable charcoal filter is listed for filtering fumes and odors. A turntable on/off setting gives you another option for larger or unusually shaped dishes.
At 40 pounds, it is the lightest model among the options listed here, but weight alone does not establish that it is suitable for an RV. Its width is substantial, and the installation should be checked against your cabinet and cooktop layout. It is a straightforward microwave choice rather than a convection appliance, so it does not replace an oven for baking or roasting.
Pros:
- 10 power levels and simple express-cook controls
- Two-speed, 300-CFM ventilation with a charcoal filter
- Turntable can be switched off for certain dishes
- Listed weight is lower than the other models in this comparison
Cons:
- Nearly 30 inches wide, so it is not suited to a 22-inch opening
- No convection cooking function is listed
Verdict: Consider the GE if your RV has a full-size installation space and you want a conventional microwave with useful venting and simple controls.
3. CAMPLUX Convection Microwave: Most Versatile Cooking Functions
The CAMPLUX combines microwave cooking, convection baking and roasting, and a range hood in one appliance. Its 1.5-cubic-foot interior is listed as large enough for a 13-inch pizza, a 9-by-13-inch casserole, or a 4-to-5-pound chicken. That added versatility can be useful when counter and storage space are limited—but only if the appliance fits your RV and its electrical setup can support the intended functions.
The microwave output is listed at 900 watts with 11 power levels. For convection cooking, the product description lists 1,450 watts and hot-air circulation. It also has a 300-CFM, two-speed vent and LED cooktop lights. Its exterior is about 29.88 inches wide, making it a full-size option rather than a compact 22-inch solution.
The manufacturer description identifies RVs as one possible setting, but this model weighs 66.1 pounds. That makes secure mounting and cabinet support especially important in a vehicle that moves. It is also important to confirm the required electrical capacity for the cooking mode you plan to use; an advertised RV use case does not confirm compatibility with every RV power system.
Pros:
- Combines microwave, convection, and ventilation functions
- 1.5-cubic-foot capacity with a listed 13.58-inch turntable
- 300-CFM ventilation and LED cooktop lighting
- Product description includes RVs among possible installation settings
Cons:
- About 30 inches wide and heavier than the other listed models
- Requires careful checks for mounting and electrical capacity
Verdict: Pick the CAMPLUX if you have room for a full-size unit and value convection cooking, provided your RV can support its weight and power needs.
4. Frigidaire 1.8-Cubic-Foot Microwave: Best for a Larger Cooking Interior
With a listed 1.8-cubic-foot capacity, this Frigidaire offers the largest interior among these five models. The product details say it can accommodate a 13-by-9-inch baking dish, which may be helpful if you regularly heat larger meals. Its exterior is about 29.88 inches wide, however, so it requires a full-size installation area.
The microwave has 1,000 watts of cooking power, one-touch cooking options, an extra-large glass turntable, and auto-reheat presets. A two-speed, 300-CFM fan handles ventilation, while LED lighting illuminates the cooktop. The zero-clearance door is described as opening to a 90-degree angle without touching adjacent walls, a useful design detail where nearby walls could otherwise interfere.
For an RV, the main questions are fit, mounting, and power—not just interior capacity. This model weighs 56 pounds and is nearly 30 inches wide. The capacity may be more than you need in a compact kitchen, so measure both the mounting area and the path needed to bring the appliance into the RV.
Pros:
- Largest listed capacity in this comparison
- 1,000 watts of cooking power and one-touch controls
- Two-speed, 300-CFM ventilation with cooktop lighting
- Door design is intended to avoid contact with adjacent walls
Cons:
- Nearly 30 inches wide, far larger than a 22-inch target
- May be oversized for a small RV kitchen or its cookware needs
Verdict: Choose the Frigidaire if capacity is your priority and your RV has a properly supported full-size opening; skip it for a genuinely compact space.
5. BLACK+DECKER 1.7-Cubic-Foot Microwave: A Shallower Full-Width Option
This BLACK+DECKER model has a 1.7-cubic-foot capacity and 1,000 watts of cooking power. Its listed depth is 13.2 inches, shallower than the other models in this group. That could help if depth is the main constraint, but it is still about 29.9 inches wide and 16.4 inches tall, so it is not a fit for a 22-inch-wide opening.
Controls include 10 power levels, six quick menus, and a multi-stage cooking feature that lets you set two power levels in one program. The product details also list a two-speed, 300-CFM vent fan and cooktop light. Its stainless steel finish and standard microwave functions make it a familiar option for reheating and everyday cooking.
Some users report that the controls are easy to use and that the unit handles routine meals well. One usability detail to keep in mind is that the control behavior may take a little time to learn. For RV installation, its shallower depth is worth comparing with your cabinet layout, but it does not resolve the width, mounting, or electrical checks required for a vehicle.
Pros:
- Shallower listed depth than the other models here
- 1.7-cubic-foot capacity and 1,000 watts of cooking power
- Multi-stage cooking and 10 power levels
- Two-speed, 300-CFM vent fan with a light
Cons:
- Nearly 30 inches wide, not a compact 22-inch model
- Control behavior may take some getting used to
Verdict: Consider the BLACK+DECKER if your RV has a full-width opening but limited depth; verify the complete installation requirements before buying.
How to Choose an Over-the-Range Microwave for an RV
Measure the Full Installation Space
Do not shop by the width in the product name alone. Measure the opening’s width, height, and depth, then compare those numbers with the microwave’s exterior dimensions. Also account for the space above and around the unit, the cooktop below it, and any nearby walls, cabinets, or trim. Of the options here, the COSMO is the narrowest at 23.8 inches, but none is 22 inches wide.
Check the Mounting and Cabinet Support
Over-the-range microwaves are mounted above a cooking surface, so the cabinet and mounting points need to support the appliance securely. Weight ranges from 40 pounds for the GE to 66.1 pounds for the CAMPLUX in this selection. In an RV, confirm that the structure and installation method are appropriate for travel, and follow the appliance’s installation instructions rather than relying on dimensions alone.
Confirm Electrical Compatibility
The COSMO listing specifies 120 volts, and several other models list 120-volt power. That information does not by itself confirm that an appliance will work with your RV’s electrical system or available power. Check the microwave’s full electrical requirements and your RV’s supply, including any limits that apply when other appliances are running. Pay particular attention to the CAMPLUX if you plan to use its convection function.
Decide How Much Cooking Capacity You Need
Capacity ranges from 1.34 cubic feet in the COSMO to 1.8 cubic feet in the Frigidaire. A larger interior can handle larger dishes, but it also may be unnecessary in a small kitchen. Check the turntable diameter and the dimensions of the cookware you actually use; cubic-foot capacity alone does not tell you whether a favorite dish will fit.
Choose the Right Venting Setup
All five models include ventilation features, but the installation details still matter. The GE, CAMPLUX, Frigidaire, and BLACK+DECKER listings specify 300-CFM ventilation, while the COSMO listing describes an integrated range hood without a CFM figure in the supplied details. Check whether your RV setup needs air recirculated through filters or vented elsewhere, and confirm that the appliance’s venting parts support your arrangement.
Consider Whether You Need Convection Cooking
A standard microwave is suited to reheating, defrosting, and microwave cooking. The CAMPLUX adds convection baking and roasting, which can provide another way to prepare food without a separate oven. That extra function comes with additional installation and electrical considerations, so it is most useful when you have the space and power to support it.
Think About Weight and Access for Installation
Make sure the appliance can be carried into the RV and lifted into place safely. Weight varies substantially across these models, and the route through doors or hallways may be tighter than the final opening. Plan for secure mounting and access to any filters or service points that need routine attention.
Frequently Asked Questions
Is there a true 22-inch over-the-range microwave in this selection?
No. The narrowest listed model is the COSMO, at 23.8 inches wide. The other options are about 29.9 inches wide, so none is an exact 22-inch match.
Which microwave is the closest fit for a compact RV kitchen?
The COSMO is the narrowest option here and is described as RV-friendly in its listing. Still, compare its full dimensions, weight, mounting needs, and electrical requirements with your RV before choosing it.
Can I install any over-the-range microwave in an RV?
Not automatically. Confirm that the cabinet can support the unit, the dimensions suit the space, the mounting method is appropriate, and your RV’s electrical system can handle the appliance. Also check the manufacturer’s instructions for installation and venting.
Which option has convection cooking?
The CAMPLUX is the only model here described as having convection cooking. It combines microwave, convection, and range-hood functions in one appliance.
Which model has the largest cooking capacity?
The Frigidaire has the largest listed capacity at 1.8 cubic feet. Its exterior width is about 29.88 inches, so that larger interior requires a full-size installation space.
Do these microwaves vent outside?
The supplied product details mention ventilation features, filters, or venting parts, but they do not confirm that every model is compatible with every RV vent arrangement. Check the installation instructions and the specific venting configuration you plan to use.
Final Recommendation
For an RV owner searching for a compact over-the-range microwave, the COSMO is the most practical starting point in this group because it is the narrowest and is described as RV-friendly. It is still 23.8 inches wide—not 22 inches—so verify the opening and installation details before ordering. If your RV has a full-size opening and you want convection cooking, consider the CAMPLUX; if you only need conventional microwave functions, compare the GE, Frigidaire, and BLACK+DECKER based on capacity, depth, and controls. No matter which model you prefer, confirm fit, mounting support, venting, and electrical compatibility first.
