AM350-X Wireless RV Leveling System Review: A Simple Way to Level Your RV

Leveling an RV or travel trailer often means getting out of the vehicle repeatedly, checking a bubble level, adding blocks, and moving the trailer again. The AM350-X Wireless RV Leveling System from AOMOSUR aims to simplify that process by showing your RV’s left-right and front-back tilt in real time, so you can make adjustments without leaving the driver’s seat.

This review explains what the AM350-X does, how it works, what is included, how to install and calibrate it, and which RV owners will benefit most.

What Is the AM350-X Wireless RV Leveling System?

The AM350-X is a wireless electronic leveling system for RVs, motorhomes, travel trailers, fifth wheels, and camper vans. It uses a small transmitter installed inside the RV to measure the vehicle’s tilt, then sends the angle data to a dedicated display or a compatible phone app.

Unlike a traditional bubble level, it does not simply show whether the RV is level. It shows which direction the RV is tilted and displays the angle in increments as small as 0.1 degrees, helping you decide whether to pull forward, reverse, add leveling blocks, or adjust jacks.

Key Features at a Glance

• Dual-axis monitoring for roll (left-right) and pitch (front-back) angles.

• Real-time angle display with 0.1-degree precision.

• Magnetic, detachable transmitter for easy installation and charging.

• USB-C rechargeable lithium battery design.

• Wireless signal range of up to 150 feet, according to AOMOSUR.

• Designed for solo RV setup from the driver’s seat.

How the AM350-X Works

The system has two main parts: a transmitter and a display or app interface. The transmitter contains a six-axis gyroscope that measures the RV’s angle. Once mounted inside the RV, it sends tilt data wirelessly to the display, allowing you to monitor the vehicle’s position while parking or adjusting leveling equipment.

The display shows both roll and pitch angles on one screen. When the measured tilt is below 0.5 degrees, the system indicates that the RV is level.

What Roll and Pitch Mean

Roll Angle: Left-to-Right Leveling

Roll measures whether one side of the RV is higher than the other. This is usually the first issue RV owners correct after parking, often by driving onto leveling blocks or using a ramp.

Pitch Angle: Front-to-Back Leveling

Pitch measures whether the front or rear of the RV is higher. On travel trailers, this often requires adjusting the tongue jack; on motorhomes, it may require hydraulic jacks or other leveling equipment.

AM350-X Specifications

The AM350-X is compact and lightweight, making it suitable for permanent installation inside an RV or trailer. The transmitter weighs about 106 grams, while the display weighs about 138 grams.

These specifications are based on the official AOMOSUR AM350 user manual and product listings.

Signal Range and Connectivity

AOMOSUR states that the transmitter uses an industrial-grade wireless design with a range of up to 150 feet. The manufacturer also says the signal can penetrate plywood and metal, which is useful when the transmitter is installed inside a trailer while the user monitors it from a tow vehicle.

What’s Included in the Box

The AM350-X package includes the main hardware needed for installation and everyday use. Exact accessories can vary by seller or package version, so buyers should confirm the contents before ordering.

Typical contents include:

• AM350-X transmitter

• Dedicated display receiver

• Magnetic mounting base

• USB-C charging cable

• User manual

• Storage bag and mounting accessories, depending on the package

The transmitter is designed for interior installation and should not be exposed to rain or mounted outside the RV.

How to Install the AM350-X

Installation is designed to be simple, but correct placement and calibration are important for accurate readings. The transmitter must be mounted on a vertical interior surface, with the direction arrow pointing upward.

Step 1: Choose the Installation Location

Install the transmitter inside the RV on a flat, vertical wall or cabinet surface. Keep it away from large metal objects, and choose a location that is easy to reach for charging and power control.

Step 2: Mount the Magnetic Base

Attach the magnetic base using the included adhesive or screws. Once the base is secure, snap the transmitter onto it. The magnetic design allows you to remove the transmitter later for USB-C charging.

Step 3: Position the Display

Place the display on the dashboard, attach it to an air vent using the magnetic mount, or hold it while setting up the campsite. The dedicated display means you do not need to keep a phone open or connected to use the system.

Step 4: Calibrate on Level Ground

Before first use, park the RV on genuinely level ground. Then press and hold the display’s up button and power button for about five seconds until you hear a confirmation tone. This saves the calibration to the device.

Step 5: Set the Transmitter Orientation

In the settings menu, select the transmitter’s installation direction, such as front, rear, driver side, or passenger side. Also select whether your vehicle is left-hand drive or right-hand drive. This helps the display give correct directional guidance.

How to Use It at a Campsite

Once installed and calibrated, the AM350-X is straightforward to use. Turn on the transmitter and display, wait for them to connect, then watch the angle readings as you position the RV.

For Travel Trailers

1. Pull into the campsite and watch the roll angle from the tow vehicle.

2. Adjust your position or drive onto leveling blocks until the left-right angle is within the desired range.

3. Disconnect and use the tongue jack to correct the front-to-back pitch.

4. Confirm that both roll and pitch readings show the RV as level.

This process is especially useful for solo travelers because it reduces the need to walk between the tow vehicle and trailer.

For Motorhomes and Class C RVs

For motorhomes, the AM350-X can help you identify whether the coach is tilted before deploying jacks or placing wheel chocks. It provides angle feedback, but it does not automatically operate jacks or leveling systems.

AM350-X Pros and Cons

Pros

• No phone required for the display version: The dedicated screen is convenient for users who do not want to depend on a smartphone app.

• Real-time dual-axis readings: You can monitor left-right and front-back angles at the same time.

• High angle precision: The 0.1-degree display resolution gives more useful feedback than a basic bubble level.

• Magnetic, detachable transmitter: Installation is simple, and the transmitter can be removed for charging.

• USB-C charging: Rechargeable batteries avoid the ongoing cost and inconvenience of replacing AA or coin-cell batteries.

• Good for solo RV setup: Real-time feedback helps a driver make adjustments without repeatedly exiting the vehicle.

Cons

• It does not level the RV automatically: The AM350-X only measures tilt; you still need blocks, ramps, jacks, or a hydraulic leveling system to make physical adjustments.

• Transmitter must be manually powered on: Some users note that you need to access the transmitter before starting the leveling process.

• Not waterproof: AOMOSUR specifies interior installation only, so it is not suitable for exterior mounting or wet environments.

• Automatic shutdown may interrupt longer setups: The display can turn off after periods of inactivity, which may require restarting during a longer leveling session.

• It shows angles, not exact lift height: It tells you the direction and degree of tilt, but not precisely how many inches or centimeters to raise one corner.

Who Should Buy the AM350-X?

The AM350-X is a good fit for RV owners who want a practical, affordable way to speed up campsite setup. It is particularly useful for people who frequently travel alone or who want clearer feedback than a manual bubble level provides.
