Dropped Axles On a Tiny House Trailer

When building your Tiny House there is a few limitations in size to adhere to, one of those being the max federal height of 13’6″ tall. How can you maximize your tiny house and still stay under that 13’6″ requirement?

  • One of the most popular ways is to use the Trailer as the subfloor as seen here.
  • the other is to use 4″ Dropped axles on your custom Tiny House Trailer.

What is the advantages of using 4″ Drop Axles?

  • They lower the deck down 4″ to approx 22″ on Tiny House Basics Trailers (on trailers with 6″ Main frame rails)
  • The Lower Deck Height Makes an Easier approach or entrance into the Tiny House
  • They increase the interior space in your tiny house where it matters most, the lofts! Many people tend to bump their heads when sitting upright in their Loft, imagine what an extra 4″ of headroom will do!


Are there any disadvantages?

  • the need to make slightly wider turns when pulling into gas station when towing a drop axle trailer. Gas stations are the only place i have ever seen that sometimes have steep curbs to enter and exit, it’s not really a disadvantage but more of a habit change when towing a drop axle trailer.

Are Drop Axles as strong as Straight Beam Axles?

  • Yes!! All Axles whether straight or dropped can handle the weight they are rated for. When choosing an axle rating for your build keep in mind the GVWR rating of the combined axles includes the weight they can handle including the weight of the trailer itself. No matter the axle style you choose, make sure to buy more “Trailer” than you think you need, because once your tiny house is build, you can not change the trailer!


What GVWR’s (Gross Vehicle Weight Ratings) Do the drop axles come in?

  • 3500 lbs (or 3.5k) Capacity – Used on our Trailers in Dual Axle Or Triple Axle Configurations
  • 5200 lbs (or 5k) Capacity – Used on our Trailers in Dual Axle Or Triple Axle Configurations
  • 6000 lbs (or 6k) Capacity – Used on our Trailers in Dual Axle Or Triple Axle Configurations
  • 7000 lbs (or 7k) Capacity – Used on our Trailers in Dual Axle Or Triple Axle Configurations

What is the cost to upgrade to Drop Axles from Straight Beam Axles?

  • $175 Per Axle Upgrade Charge on 5k, 6k, 7k Axles

    Good Job on the drop axle story. Most gas stations if you enter at a angle to the entrance you will be in good shape not to scrape the bottom near the back corners. Keep up the good work

    So if both dropped axles are used and sub flooring the trailer, then does that add about 8 inches more of headroom to lofts?

    1. Joshua Engberg

      With drop axles you will gain 4″of headroom in the lofts, if you use the trailer as the subfloor you will gain a additional 3.5″ of space as well

    Q: 1 – Can you build a 34-footer with just 2-Axles? ____
    ….(Standard height). I wish to build a “Travel Trailer” on your Frame.
    Interior (floor to ceiling) height is only 8 to 9 feet. Therefore, I will not have a Sleeping Loft.
    Ground to floor height is okay because I really would like to have Storage compartments along each side.

    Q: 2 – And why do you prefer Electric Brakes vs. Disc Brakes?___

    Q: 3 – Are you using “U-shape Channel Steel, or are you using Rectangle Steel Tubing for your cross members? ____

    1. Joshua Engberg

      We would recommend a minimum of triple axles for that size. We only offer electric brakes on our trailers. We use box tube on all our trailers.
