SketchUp Trailer File for Tiny House Drawings


I’m beginning to build a publicly available library of SketchUp drawings for those using this free 3D illustration software to draw their own tiny houses. In time you’ll be able to search the category SketchUp Files and find all the available files.

This first file is a simple to use trailer drawing, based loosely on the Big Tex Trailer specifications. I have no affiliation with Big Tex, I just like the fact that they publish their dimensions online.

If you do some trailer shopping, virtually or in person, you’ll find that few trailers are alike. So I’ve made this simple trailer drawing easy to adjust to the exact size of the trailer you buy for your project. This way you’ll be able to draw your tiny house design to fit on the exact size of your trailer.

In the SketchUp file you’ll find three trailers. They are all exactly the same except that I’ve resized the length to 14-feet, 16-feet, and 18-feet. All three measure 82-inches between the fenders. Just open the file, then copy and paste the size trailer you want to start working with into your own drawing. Be sure to adjust the trailer before you start your drawing.

The main measurements to focus on are:

  • Deck height – The height of the flatbed deck from the ground. Since tiny houses need to be under 13-feet 6-inches to be legally towed without a special move permit (in most U.S. states), the deck height can impact to height of the walls and roof pitch.
  • Position of the fenders – Focus on the front of the trailer to the start of the fender, from the rear of the trailer to the end of the fender, and the height of the fender from the top of the deck. Your side walls will need to wrap around and over the fender.
  • The width between the fenders is normally 82 or 83-inches for 8.5-foot wide trailers. You might also be wondering how a 102-inch wide trailer would only allow for 82 inches between the fenders – the simple answer is that the fenders are fairly wide themselves.

Stay tuned for more drawings in the next few days and weeks.

    You are awesome. I’m 26, living in Denver and starting my tiny house dream wall now. I’ve started my google sketchup tutorials and thanks to this handy and awesome trailer template, i’m well on my way to designing my dream home. Yay for open source! I promise to share my final design with you and the world when finished. :-) Cheers, Lauren.

    Question, Michael – any reason I can’t use a gooseneck lowboy trailer instead of a bumper-pull? I see Big Tex has dimensions for those as well, and it’ll pull a lot easier than a bumper-pull trailer.

  6. There’s no reason I know of. I think people choose flatbeds for aesthetic reasons mostly.

    O.k. I feel like this is a dumb question but where and how is everyone downloading this file from? I have somehow missed that. Thanks

    Is there anyway to get a 20ft deck over trailer sketchup or has that not been designed before on sketchup? Cause I’d like to use one in my design but have no skills toward making one myself. thank you
