Stirling Trailers manufactures lightweight, single-axle trailers designed for homeowner use, including utility trailers, boat trailers, and unassembled trailer kits. All trailers are constructed from durable Galvalume Plus™ steel for long-lasting performance.

All Stirling trailers come equipped with a 4-way flat electrical connector which is used to power the trailer’s exterior lighting and signaling functions. This connector supports the running lights, brake lights, and turn signals required for safe road use.

The standard wire color coding is as follows:

• White – Ground
• Brown – Running lights (split to both driver and passenger sides)
• Yellow – Left turn signal and brake light
• Green – Right turn signal and brake light

This standardized wiring configuration ensures compatibility with most passenger vehicles and light-duty trucks.

The required hitch ball size depends on the trailer type and model year. Please refer to the details below to ensure proper fit and safe towing.

When the trailer is level on flat ground, the approximate hitch height (measured from the ground to the coupler) is:

• Solid Side & Rail Side Utility Trailers: 15″
• Boat Trailers: 14″
• Trailer Kits with 8″ wheels: 13″
• Trailer Kits with 12″ wheels: 15″

Galvalume Plus™ is a premium protective finish designed to extend the life of your trailer. It combines aluminum, which shields against moisture and weather, with zinc, which protects the steel if the surface ever gets scratched. A small amount of silicon helps the coating bond tightly to the steel, and a clear protective top layer adds an extra barrier against the elements, giving your trailer a consistent, even finish that maintains its appearance over time.

Most provinces and states require trailers to be registered before they can be towed on public roads. Registration requirements vary by location, so you should always confirm the specific process with your local transportation authority.

Canada

Before registering your trailer, the New Vehicle Information Statement (NVIS) must be completed by the dealer and signed by you. To register your trailer, take the following documents to your provincial Ministry of Transportation:

• Bill of Sale
• Completed NVIS

After paying the applicable provincial fees, your trailer will be registered, and a trailer license plate will be issued.

États-Unis

Before registering your trailer, the Certificate of Origin must be endorsed by the dealer. To register or title your trailer, bring the following documents to your local Department of Motor Vehicles (DMV):

• Bill of Sale
• Completed Certificate of Origin

Once state fees are paid, the trailer will be registered and/or titled. The DMV will then issue a Certificate of Title or other official ownership document.

For more details, see Registering Your Trailer. If you experience any issues registering your trailer, please contact info@stirlingtrailers.com and include proof of purchase and the trailer VIN. Our team will be happy to assist.

For most trailers, yes. Galvalume Plus™ combines aluminum’s natural barrier with zinc’s ability to protect steel if the surface gets scratched, giving longer-lasting corrosion protection than aluminum alone. Plus, because it’s applied to steel, it’s stronger and more durable, making it ideal for rain, snow, sun, and years of regular use.

The gate is designed to safely support up to 50% of the trailer’s payload capacity.

To determine whether your vehicle can safely haul a trailer, you’ll need to understand the trailer’s weight ratings and compare them to your vehicle’s towing and payload limits.

You can calculate key trailer weight values using the following formulas:

• Maximum Payload = GVWR − Trailer Weight
• GVWR = Maximum Payload + Trailer Weight
• Trailer Weight = GVWR − Maximum Payload

Once you know the trailer’s GVWR and loaded weight, consult your vehicle’s Owner’s Manual or manufacturer specifications to confirm its towing capacity, payload rating, and GVWR. Your vehicle must be rated to handle the fully loaded weight of the trailer to ensure safe, legal operation.

If you’re unsure, our team or your dealer can help you select a trailer that matches your vehicle’s capabilities.

Side availability varies by trailer type:

Trailer Kits: Some kits come with rail sides included, while others are sold as open frame only. If you purchased a frame-only kit, you could always buy the rail sides separately later, giving you the flexibility to build and customize your trailer your way.

Solid Side Utility Trailers: Our solid side utility trailers come standard with 15″ sides. We do not currently offer taller side options.

Rail Side Utility Trailers: We do not manufacture side panel options for rail side utility trailers.

Only boat trailers are equipped with lights designed for submersion. Lights on other trailer types are not intended to be submerged.

Please also note that exposure to different water types such as freshwater or saltwater can affect the trailer’s Galvalume Plus™ finish over time. Rinsing the trailer after water exposure is recommended, especially after contact with saltwater.
