Whether you're buying a trailer for personal use or purchasing for a large company, there are many factors to weigh before making your purchase. An utility trailer may be the perfect fit for some, others may have completely different requirements.
Before you buy a trailer, consider the following questions:
Trailer Axles
There are two main axle options when choosing a trailer - single axle and tandem axle. A single axle trailer has two wheels while a tandem has four. Deciding between an axle type comes down to weighing the advantages and disadvantages of each against what you need in a trailer.

Single Axle - 2 Wheel
There are many advantages to a Single Axle Trailer:

Tandem Axle – 4 Wheels

Pull Type
Choosing between a Bumper Pull Trailer and a Gooseneck Trailer comes down to what your vehicle's towing capacity and your towing needs. If you have an SUV and need to tow something on the lighter side, then a bumper pull trailer may be the better choice. These trailers are typically smaller and much lighter, which leads to being less expensive. However, if you need a larger payload capacity, then you'll want to consider a gooseneck trailer.
Trailer Condition - Should I Buy New or Used?
When deciding between purchasing a new or used trailer, there are a handful of factors to consider.
What are the potential Repair Costs?
Like with any product that has prior use, there will be differing levels of wear and tear. Depending on the circumstance, a used trailer may require repairs sooner than a new trailer.
What's the Cost?
Often a used trailer will be half or even less of the sticker price of a new trailer.
What is the Long-Term Practicality?
While the upfront cost of a new trailer is higher, you could go years without needing any major repairs or replacements. This may not be the case for a used trailer. The initial difference may be several thousands of dollars between a new and used trailer. However, after a few years, that difference could easily even out with the repair or replacements costs of a used trailer.
