Customizing Race Trailers

There are literally hundreds of different issues to consider when designing a race trailer. These are the top most important considerations:
  1. Size
  2. Weight
  3. Living Quarters
  4. Flooring
  5. Car Loading
This article will take some of the most popular and important selections when designing a race car trailer.


The size of race trailers is normally 2 dimensional. The maximum width for any vehicles in the United States is 102″. Most race trailers are 102″ wide therefore the two dimensions that need consideration are the height and the length.


trailer must be able to accommodate the height of any type of vehicle, in this case we are writing on race car trailers. Normally race cars are lower to the ground and not very tall. A race trailer can be configured to be a Stacker Trailer which allows cars to be on two levels in the trailer. In this case the trailer must be tall enough to load two cars plus some buffer space in between the roof of one car and the trailers of another. Standard interior height for a race trailer is normally 6’6″. If any person that will be in the trailer is taller than 6’6″ the trailer height should be expanded. Trailers that are taller naturally feel bigger, because the are, this gives a better feeling in a living quarters. If the trailer is being used for another purpose you should also consider the height of anything being loaded. An 11′ interior is normally the maximum height. Finally consider the ramp door height.
Ramp Door Opening Height
st be rolled into the trailer so the door must be tall enough to accomplish this.  Just because height was added to the interior of the trailer does not mean that the ramp door opening has also been increase.  When loading you must also consider the angled approach so do not keep a low tolerance in this area.
Exterior Trailer Height
major factors impact exterior trailer height.  The interior height an the tire size.  Increasing axle size can increase exterior trailer height.  Two import considerations of exterior height are resting place of the trailer and path needed to travel.  Some people like to keep their trailer indoors, if you are one of these people ensure the trailer will fit.  If you have an air conditioner or other option on the roof, do not forget the clearance for these items.  In some cases you may need to pass under a low bridge or other area with minimum clearance.  Consider this in your purchase.

Overall Length

Many other items are going to be loaded in a race car trailer, other then the car itself. Consider all the items that you may take to the track. 5 of the most popular items are:
  1. Fuel
  2. Tools
  3. Air Compressor
  4. Golf Cart
  5. Camping Equipment
Loading Fuel
Two types of fuel are often carried by race teams. First is the fuel that will be used in the race car. This is a very specialized type of fuel and is normally stored in fuel jugs and kept it a fuel jug holder. This holder can be a stainless steel holder with the jugs sitting on the ground
Tools Needed to Maintain the Car at the Track
Almost without exception race teams need to work on their car inside the race trailer. A wide variety of tools are needed to accomplish maximizing race results. Tool chests can be added to a trailer just like the ones in the garage. These chests need to be bolted to the race trailer floor so they do not move during transport. Some teams provide their own tool chest while others have them installed by the factory.
Air Compressor with Air Lines
Many of the tools that are carried by the team operate on air power. Impact wrenches, air rachets and more are used to make any manual job easier and faster. A trailer with an air compressor and air lines ran in the trailer can facilitate this need
Transportation Around the Track: The Golf Cart
The team needs to be transported around the track quickly and almost all teams have a golf cart so that they can move about the track with ease. Loading golf carts into race trailers can be a tricky job. Most people drive it in and park it cart nose to wall but others include a golf cart ramp
Camping Equipment
When at the track you may need basic camping gear if you are staying on site. Storing that gear for easy access and out of the way is important. Trailer cabinets can be ideal for this.
Pulling it all Together
Graph paper or CAD system to place all your items loaded into the trailer. Consider unloading as well and such items as tie downs. It is not feasible to change the length of the trailer so once you buy the trailer.  Sometimes the best price can get achieved by buying a longer trailer in stock.  Keep in mind when shopping for a gooseneck trailer, the floor length is generally 8 feet less than the overall trailer length due to the eight foot overhang that is over the truck bed.

Weight, Gross Vehicle Weight Rating

eight of all items put in the trailer should be tallied or closely approximated. This calculation is the payload. Every trailer built will be given a GVWR, this is the Gross Vehicle Weight rating, the maximum amount the payload plus the trailer can weigh. For example a trailer with triple 7,000# axles would have a GVWR of 21,000#, therefore if the trailer weighed 8,000# the payload capacity would be 13,000# so all the items loaded in the trailer cannot exceed 13,000#. The tow vehicle rating will be in the GCWR or Gross Combined Weight Rating is the weight of the trailer loaded plus the weight of the tow vehicle. If the GCWR is 19,000# and weighs 7,000# the loaded trailer including the trailer itself cannot exceed 12,000#. This information is provided as is and may not be correct. Consult your tow vehicle dealer for specific numbers.  Aluminum trailers can be considered to lower the weight slightly.

Living Quarters and Other Household Comforts

amenities can be added to race car trailers. The top five amenities are:
  1. Bathroom
  2. Bed
  3. Refrigerator
  4. Sink
  5. Microwave
  6. Entertainment
These items can be purchased a la carte or in a complete package. Bumper Pull Living Quarters floor plans can be viewed and contents of the packages displayed. Custom floor plans can be provided via a la carte items and packages for bath rooms and kitchens. Partition walls can be added to keep garage and living area separate. Consult with your Millennium Trailers design specialist for details at 800-978-7223.  A bathroom can be a critical need for a family spending the a day or days at the track.


Generally there are two classifications of bathrooms, wet bat and dry bath.  A wet bath enclosed the shower and toilet in one area, why a dry bathroom has a separate shower and toilet.  There are many other considerations in the bathroom, such as size of the shower.  

Bed to Sleep On

  A gooseneck trailer often offers the best solution for a bed.  The area in the gooseneck offers a perfect location for 1 large bed or two small beds.  A couch and dinette often times can be converted into a bed.  In the garage area you can also consider a fold down bench/bed combo or a bed that stores near the ceiling when not in use.

Refrigerator Requirements

There are several sizes of trailer refrigerator, the most common are between 3 and 8.  A refrigerator must be vented and in some cases be run on electric or propane.


Consider the use of a sink. Some people just want a place to wash their hands, others are looking to wash dishes or more.  Usually a sink is installed in the bathroom so that minimal sink may be good enough.

Entertainment Systems

There can be a good amount of downtime at the track.  Trailers offer virtually any entertainment that a home can.  TV, radios and satellite dishes are all very popular.   Kitchen of a Race Trailer with Living Quarters

Floor Coverings

The top types of floors for race car trailers are:
  1. Rubber Coin
  2. Vinyl
  3. Aluminum Trade Plate
  4. TPO
  5. Carpet
Each flooring types offer different advantages, but the most popular type of flooring is rubber coin. Rubber coin offers durability and a more slip resistant texture. ATP offers a very durable surface but is prone to slippages when fluids are spilled. TPO is a thin, hard plastic type material that is very durable. Think about your situation and what works best. Cost may also become an issue on larger trailers. Rubber Coin Floor

Loading Race Car Trailers

The two most popular ways to load a race trailer is driving the car into the trailer or using a winch to pull the car into the garage area. The advantage to driving the car into the trailer is a lower cost without a winch. The two drawbacks are getting out of the car and if the car is damaged and does not run it cannot be driven in. A key factor when loading a car is ground clearance. The approach loading angle can be altered by increasing the ramp length with race car trailer accessories known as ramp extensions and raising the ramp door with bumpers. Most car trailers are equipped with a beaver tail which is a slight incline leading up to the floor of the trailer which is flat. Beaver tails can also be extended to accommodate very low cars. The bottom line is that you are buying this trailer to take your race car to the track. If it is too low to the ground and the bottom rubs the trailer damage can occur to both the trailer and the car. Work with your Millennium Design specialist to get all the features that are required.

Final Thoughts and Important Buying Considerations

Normal enclosed car trailers can be used for a race trailer, but to get the most out of the race car trailer the considerations above are crucial.  Most of the time a custom trailer will be more expensive than a trailer on the lot, but this is because you get many more features that you want.  If your needs are minimal a custom trailer may be less expensive because unwanted options are not in the price.
