Choosing a Trailer Choosing the Right Utility Trailer
 

... A Few Things to Consider

Utility Trailers
There is a lot to consider when choosing a trailer -- especially a utility trailer.  There are so many choices and options available.  This guide is intended to help navigate the possibilities.  Use the questions and thoughts to make a list of requirements and the things you think are important, then use that list to choose the right trailer for you.

You may also want to read our feature on "What makes a good trailer design."


First Step:  Discover the need:
Obviously the trailer must first meet the need -- how will it be used?  It's not enough to say "I need a trailer to haul building supplies."
Is that bricks?  ...  10 Penny nails?  ...
...  Or 2 x 6 x 20's?
The truth is, if your situation is like most, the trailer will also be used for a lot of other things like moving furniture, hauling leaves, rocks and other equipment.

Think through your needs and all the possibilities (like your friends needs, your wife's needs, and your wife's friends needs - Yes, I've been there).  Knowing how the trailer will be used can guide your decisions to the best trailer for you.

Consider the following questions about how the trailer will be used:
  • How big should it be?
  • Width: 4'?  5'?  6'?  8'?
    (What are the legal limitations in your state or province?)
  • Length:  8'?  10'?  20'?
    (Where will it be stored?)
  • What load capacity is required?  1000#?  2000#?  3500#?  6000#?  More?
  • Is the bed height a factor?
    (How will you be getting things on and off?)
  • Does it need sides?
  • Does it need a top?
  • Does it need ramps?

Step 2:  Towing:
Is Your Trailer Hitch This Good?

The second factor to consider is how the trailer will be towed.

- Is the trailer to be a truck replacement?
- Will it be towed by the family car?
- Maybe a mini-van?  Or an SUV?

- Is the trailer to augment the capacity of your truck?
- Or haul specific equipment?

These questions are a good guide for trailer size.  Each vehicle has a towing capacity.  Check the owners manual to see that your needs can be met with the vehicle you have in mind.

The trailer must meet the needs, but it must also be sized for the vehicle that will pull it.  If your vehicle does not have a receiver (ball to hitch the trailer to) make sure you can mount one.  There are lots of places that specialize in hitches.  www.etrailer.com or www.reese-hitches.com are good places to start.

Here are some more questions to think about with respect to towing:

  • What vehicle(s) will tow the trailer?
  • What is the towing capacity of the tow vehicle(s)?
  • Can a trailer hitch be mounted to the vehicle?
  • What is the height of the hitch point?
  • Will the trailer need brakes?  Hydraulic?  Electric?

Step 3:  Storage:
A consideration which is often overlooked -- Where will the trailer be stored?  The answers to these questions will help determine your needs for trailer finish and shelter.  They may also impact your decisions on trailer size.

A trailer stored out under a tree.
  • Will the trailer be stored in a garage?
  • If in a garage, will it be tipped on it's side or end to make room for a car?
  • Will it be stored outside?
  • If outside, what shelter from the wind, moisture and sun are available?
  • How much space is available for storage?
  • Is the access convenient and easy?  Or will it make the trailer difficult to use?
Whether you choose to build a trailer, or purchase something new, the investment is well worth protecting.  On the other hand, if you can scrounge a cheap trailer to fill your need, shelter or protection may not be worth much.
Now that you have an idea of your trailer requirements, it's time to examine what makes a good trailer design.
