Choosing the right cargo trailer interior panels can be overwhelming, especially if you're new to trailer customization. Most standard cargo trailers come with a basic interior setup, but upgrading to custom panels can greatly enhance functionality and aesthetics.
You can choose from various materials, including plywood, aluminum, and composite panels. Plywood is a popular choice due to its affordability and ease of installation.
To ensure durability and resistance to moisture, consider using marine-grade plywood or aluminum panels. These materials are specifically designed to withstand harsh weather conditions and heavy use.
When selecting interior panels, consider the weight capacity and load-bearing requirements of your trailer. A well-designed interior can significantly impact the overall performance and safety of your cargo trailer.
Types of Trailer Panels
¾’’ Plywood Walls make a trailer more equipped to resist the elements, adding additional protection from rain, snow, the sun, and other environmental factors.
This increased thickness provides a more durable trailer overall, making it a great upgrade for hauling prized cargo.

Metal Wall Liner adds a sleek look while providing protection to your trailer walls from dings and scuffs.
White Vinyl Walls is a very economical way to achieve a clean look and added protection from dents and dings.
ATP Covered Wheel Wells dramatically increase the level of protection and add a slip-resistant surface to stand on when moving about inside the trailer.
Here are some types of trailer panels to consider:
- ¾’’ Plywood Walls: adds additional protection from elements and a more durable trailer overall
- Metal Wall Liner: adds protection to your trailer walls from dings and scuffs
- White Vinyl Walls: economical way to achieve a clean look and added protection from dents and dings
- ATP Covered Wheel Wells: adds a slip-resistant surface and increases protection
- Insulated Walls: helps combat extreme temperatures outside by keeping the inside of your trailer at a comfortable temperature
Design and Aesthetics
The design and aesthetics of your cargo trailer's interior are just as important as its functionality. FRP liner panels offer a smooth, seamless finish that enhances the overall look of the space.
This finish creates a cohesive and polished appearance, making the space feel more inviting. The absence of visible seams or joints is particularly valuable in trailers, where every inch counts.
FRP liner panels come in a variety of colors, textures, and patterns, giving you great design flexibility. Whether you're going for a modern, rustic, or eclectic look, you can find FRP panels that fit your vision.
With these panels, you can maintain a consistent and harmonious design throughout the trailer, from the kitchen to the bathroom and beyond.
Materials and Construction

Traditional materials like wood paneling and plywood have been used for trailer walls, but they can be susceptible to moisture damage and may lack insulation efficiency. However, Stabilit America's Fiberglass fiberglass-reinforced plastic (FRP) liner panels offer a revolutionary alternative with superior insulation properties and insect- and pest-resistance.
These panels combine the strength of fiberglass with advanced composite materials, resulting in trailer interior wall panels that are highly energy-efficient and provide UV protection. FRP liner panels can help maintain consistent indoor temperatures while ensuring the longevity of the trailer's interior design.
To make enclosed trailer walls sturdier, consider upgrading with options like ¾’’ Plywood Walls, Metal Wall Liner, or White Vinyl Walls. These upgrades can add protection from the elements, dings, and scuffs, and provide a more durable trailer overall.
Here are some options to consider when upgrading your trailer walls:
- ¾’’ Plywood Walls: adds additional protection from the elements and a more durable trailer overall.
- Metal Wall Liner: adds protection to your trailer walls and provides a sleek look.
- White Vinyl Walls: achieves a clean look and added protection from dents and dings.
Floor Panels for Trailers
Floor panels for trailers are a crucial aspect of their construction. They can make all the difference in the durability and performance of your trailer.

Skid-resistant underlayment can be a great option for trailer floors. This type of underlayment provides traction under both wet and dry conditions, reducing the risk of slipping and falling.
Protecting the subsurface from oil, solvents, and grease is also essential for trailer floors. A good underlayment can help prevent damage from these substances.
Washable underlayment is another advantage of using skid-resistant underlayment. It can be easily cleaned with soaps, cleaning agents, and pressure washers.
A "like new" look can be maintained longer with a good underlayment. This is especially true for trailer floors that are exposed to heavy use and harsh conditions.
If you're hauling heavy loads, consider upgrading to a ¾’’ Pressure Treated Plywood Floor. This type of floor offers greater resistance to moisture, insects, and fire.
For extra-heavy loads, a Double ¾’’ Plywood Floor is a good option. This type of floor provides 1.5” of plywood to hold the weight, making it ideal for machinery and vehicles.
Here are some options for upgrading your trailer floor:
- ¾’’ Pressure Treated Plywood Floor
- Double ¾’’ Plywood Floor
- Black & White Floor Tile
- ATP (Aluminum Tread Plate) or RTP (Rubber Tread Plate) on floor
- ATP or RTP on Ramp/flap
- Aluminum ATP Transition Flap
Trailer Wall Materials

Trailer walls play a crucial role in maintaining the structural integrity and comfort of enclosed trailers. Traditional materials like wood paneling and plywood have been used for decades, but they often lack durability and energy efficiency.
Wood paneling and plywood are susceptible to moisture damage, rot, and insect infestations, which can lead to costly repairs and replacements over time.
Stabilit America's innovative solutions offer a revolutionary alternative to traditional materials. Their Fiberglass-reinforced plastic (FRP) liner panels combine the strength of fiberglass with advanced composite materials.
FRP liner panels provide superior insulation properties, helping maintain consistent indoor temperatures while offering UV protection and ensuring the longevity of the trailer's interior design.
Here are some key benefits of FRP liner panels:
Considering the unique challenges faced by trailer owners, consulting experts like Stabilit America is crucial when choosing the right material for trailer walls.
Connecting HDPE Pieces
Connecting HDPE Pieces is a straightforward process that can be done in two ways.
One way to connect multiple pieces of HDPE is by overlapping them and using double-sided seam tape.
You can also butt the ends together and use 17 mil single-sided seam tape to create a solid connection.
