More About The Design Features

More About The Design Features

Plans are fully engineered and include easy to follow, illustrated instructions, with a parts list, and recommendations for materials and components.  Then, because it’s your trailer, we include options for customizing — so you can build it to do what you want.  (See the images to view some of the options.)

We recommend looking through the options, then choose the ones that will make the trailer perfect for you.  Use our ideas, or some of your own.  While you may want a simple plain trailer, there are options too.  A top, sides or tailgate.  Maybe a ramp, a tongue mounted toolbox, tie-down bars, or something else.
