EZ Loader Trailer Model Guide
Understanding EZ Loader trailer model numbers can make it much easier to compare trailers and choose the right setup for your boat.
Each model number is designed to describe how the trailer is built, what size boat it fits, and how it is configured. In many cases, understanding these details ahead of time can save a lot of confusion when comparing options.
Once you know how to read them, you can quickly narrow down your choices and avoid selecting the wrong trailer.

What the First Letter Means (Aluminum vs Galvanized)
One of the first things to look for is whether the model starts with a letter.
• Models starting with “A” indicate an aluminum trailer
• Models without a letter are galvanized steel trailers
For example:
A73BS 14-17 1650 – Aluminum trailer
73BS 14-17 1650 – Galvanized trailer

Understanding Trailer Width (64, 73, 90, 96, 102)
The first number in the model typically represents the approximate trailer width.
Typically, this measurement is generally taken from Outside Fender to Outside Fender and gives you an idea of the overall stance of the trailer. In most cases, wider trailers are used for larger boats. (Wheelbase)
Common examples include:
• 73 = Narrow frame (smaller boats, jon boats, lightweight setups)
• 90 / 96 = Mid-width trailers (most fishing boats, bay boats)
• 102 = Wide frame (larger boats, pontoons, tri-toons)

Boat Length Range (14–17, 20–22, etc.)
The next set of numbers indicates the typical boat length range the trailer is designed to support.
For example:
14–17 = Designed for boats approximately 14 to 17 feet long
However, this range is only a guideline. Hull shape, bow eye location, and weight distribution can all affect fitment.
In many cases, a boat may fall slightly outside this range and still fit properly.

Carrying Capacity (Weight Rating)
The final number represents the trailer’s carrying capacity.
For example:
1650 = 1,650 lb capacity
The weight should include:
• boat weight
• motor
• fuel
• batteries
• gear
Because of this, it’s important to consider the fully loaded weight of your boat when selecting a trailer.

Bunk Style and Axle Type (Letters in the Model)
Letters in the middle of the model describe how the trailer supports the boat and how it rides.
• B = Bunk style trailer (most common for fishing boats and V-hulls)
• S = Spring axle (leaf spring suspension)
Additional configurations include:
• TA = Tandem axle (two axles)
• TIA = Triple axle (three axles)

Example Model Breakdown
Let’s break down a common model:
A73BS 14-17 1650
• A = Aluminum frame
• 73 = Trailer width
• B = Bunk style
• S = Spring axle
• 14–17 = Boat length range
• 1650 = Carrying capacity
For newer model years, some trailers may have updated capacity ratings or minor design changes.

Why Model Numbers Matter
Two trailers may look similar; however, differences in width, capacity, or axle configuration can significantly affect how your boat loads, tows, and launches.
In addition, small differences in setup can impact long-distance towing and ramp performance.
In many cases, taking a few measurements before choosing a trailer can prevent a lot of frustration later at the ramp.
Understanding these details ahead of time can save a lot of confusion when comparing options.
You can also review real-world examples in our boat trailer sizing guide to see how these measurements apply in actual trailer setups.
