Enclosed trailers are one of the most secure and weather-resistant ways to transport your cargo, protecting gear from theft and the elements. At Noteboom RV, serving Sioux Falls, SD, Sioux City, IA, and surrounding areas, we carry a wide selection of enclosed trailers for sale that combine durability and practicality. Whether you haul motorcycles, tools, or trade equipment, this buying guide will help you make an informed choice.


1. Make a Budget

Enclosed trailers come at a range of price points. Think about what your limit is, which will let you eliminate options outside of that at the start of your search. No use wasting time learning about models that are beyond your budget!

As you set the number, you'll want to consider a few factors.

  • how long you want the enclosed trailer to last: if this purchase needs to last you for many years, spend extra to ensure durability.
  • how often you'll use the enclosed trailer: the more often you will use the enclosed trailer, the more you will want to invest in features to make your work easier.
  • when you need the enclosed trailer: you can save money by buying during the off-season.

Also factor in additional costs such as trailer registration, insurance, maintenance, and modifications like interior tie-downs or upgrade packages. Budgeting only for the base price may leave you unprepared when selecting features or adding accessories.


2. Pick an Enclosed Trailer Material

Most enclosed trailers are either made primarily from aluminum or steel. Each material offers perks.

Aluminum enclosed trailers:

  • are usually lighter, which can make towing easier
  • won't guzzle as much gas to tow
  • are more immune to rust

Steel enclosed trailers:

  • are usually longer lasting
  • stand strong against general wear and tear
  • are easy to get fixed since more welders work with steel

Aluminum trailers are lighter and resist rust better, which helps with fuel efficiency when towing. Steel trailers, while heavier, typically cost less per square foot and are easier to repair in rural areas. If you plan to haul heavy loads or travel long distances in Iowa, Nebraska, or South Dakota, consider the weight differences carefully to avoid overtaxing your tow vehicle.


3. Determine the Right Outer Skin Thickness

Some enclosed trailers have thin outer skin while others have thick outer skin. You'll get better protection and durability with thicker skin, but the extra material does increase the price. If you'll be hauling through tough terrain and harsh weather conditions, it's wise to invest in thicker outer skin.

4. Pick a Roof Shape

There are two common roof shapes: rounded or flat.

Enclosed trailers with flat roofs:

  • are usually more affordable
  • tend to collect rainwater and debris on the roof, which means you'll need to clean the roof more often

Enclosed trailers with rounded roofs:

  • are usually higher in price
  • have a little bit more internal height, allowing you to pack a little bit more for each load
  • allow rainwater and debris to more easily slide off of the roof, which means you won't need to spend as much time cleaning

In flat-roof designs, regular cleaning and sealing is crucial to avoid pooling water or debris buildup. With rounded or arched roofs, leaves and snow slide off more easily, reducing the frequency of maintenance. For heavy winter use in the Midwest, a curved roof is often preferred for longevity and ease of care.


5. Determine Your Ideal Enclosed Trailer Size

Some enclosed trailers are compact, others are massive, and others are somewhere in-between. The goal is to get a good balance. You don't want to get a model that's too big and end up paying for space you never use. You also don't want to get a model that's too small and end up making multiple trips. Some people base the enclosed trailer size off of their average load while others base it off of the largest load they will carry. Enclosed trailers are usually between 5' and 8' wide and 8' and 32' long, making it easy to find the perfect size for your needs.

Think beyond daily loads — if you ever expect to haul gear for a race team, landscaping business, or seasonal projects, leave headroom and length margin rather than packing the trailer to its absolute capacity. Also consider interior height if you’ll stand upright or load tall equipment. Many buyers find 7’ to 7.5’ interior height to be the sweet spot.


6. Inspect the Quality of Each Enclosed Trailer You Find

Pre-Purchase Inspection:

  • Verify the frame rails, cross-members, and welds for cracks or corrosion.
  • Check door alignment, hinges, and the operation of ramp/gate mechanisms.
  • Examine floor integrity—especially at the tie-down points—for rot or flex.
  • Test lighting, wiring, and trailer plug compatibility (e.g. 7-pin vs. 6-pin).
  • Confirm brake system (electric or hydraulic) is properly installed and functioning.
  • Look for adequate ventilation and roof vents pre-installed or prepped.
