Buying your first enclosed car trailer can be intimidating. Unlike hauling general cargo, transporting a vehicle requires precise measurements and the right structural features to ensure safe loading, proper security, and legal compliance. The wrong size trailer can damage your car or leave you stranded.
Let TrustyHaul take the guesswork out of the process. We help first-time buyers match their vehicle to the perfect hauler. Start comparing our high-quality enclosed car trailers here: TrustyHaul Enclosed Car Trailer Inventory.
1. Interior Dimensions: Measure Twice, Buy Once
Accuracy in measuring your vehicle is non-negotiable for an enclosed trailer purchase.
- Length: Measure your vehicle from bumper to bumper. Add at least 3 to 4 feet of buffer space to the overall interior length of the trailer. This space is essential for maneuvering around the vehicle to secure tie-downs and for opening the rear ramp door without hitting the car.
- Height: Measure your vehicle from the ground to its highest point (often a spoiler, antenna, or roof rack). Add at least 1 foot of clearance to the interior height specification. This prevents scraping lights or spoilers on the ceiling when loading/unloading, especially on uneven ground.
2. Axle Types and GVWR: Supporting the Load
The axle configuration dictates the trailer’s stability and legal carrying capacity.
- Tandem vs. Triple Axle: Most car trailers use tandem (two) axles. If you are hauling a very heavy vehicle (large vintage truck, heavy SUV) or if you plan to carry substantial equipment, tools, and spare parts, a triple axle may be required. Triple axles offer superior weight distribution and redundancy in case of a flat tire.
- Gross Vehicle Weight Rating (GVWR): Ensure the trailer’s GVWR (trailer weight + cargo weight) is comfortably above the total expected loaded weight. A higher GVWR is safer and allows for future equipment additions without risking legal violations.
3. Frame and Flooring Features for Security
Specialized construction features enhance usability and protection for your valuable cargo.
- Drop Axles: Many dedicated car haulers use drop axles, which are designed to sit the trailer chassis lower to the ground. This drastically reduces the approach angle of the rear ramp, making it safer and easier to load low-clearance sports cars.
- Flooring: Look for durable floor materials like rubber coin flooring or vinyl tile. These surfaces provide excellent grip for securing the car and are easy to clean after messy transport.
4. The Essential Escape Door
If you plan to haul any low-profile car, an escape door is a mandatory feature, not a luxury.
- Function: An escape door is a specialized side door—often oversized—that is positioned over the driver’s side front wheel well.
- Necessity: Once a wide or low-slung car is loaded and properly positioned inside the trailer, there may be insufficient space to open the car’s door and exit. The escape door allows the driver to step out of the vehicle and walk out of the trailer without having to crawl through the passenger side.
Making these critical choices upfront ensures you purchase a durable, safe, and fully functional car hauler. To configure the perfect trailer with the right axles and dimensions for your vehicle, visit the TrustyHaul Homepage.
