All in all, I spent about $500 total on this project (including a used $120 Harbor Freight utility trailer) , and this teardrop trailer is about as barebones as you can get. But it works, and it keeps you dry and warm.
Step 1: First step: Design Your Teardrop Trailer
At some point, I became aware of the teardrop trailer, which is a tiny little trailer that is meant only for sleeping, and offers some accommodation for fairly comfortable food prep and outdoor cooking.
I figured building a teardrop trailer was a project I felt I could pull it off from design to finish by myself, so I started by searching the internet for more info. The reason the teardrop is so popular is that its rounded profile makes it a breeze to pull behind even a car.
I decided to make a traditional style of teardrop – one with a removable galley for easy loading, and two doors. Here is a photo of my initial design idea, done in Google Sketchup – a free program offered by Google. The truck is my GMC Sonoma – a V6 capable of towing a tiny trailer, but not much else.
The Teardrop Design
First, I drew a quick sketch of what I wanted it to be. I didn’t want to reinvent the wheel (my first time around), so I went with a traditional route. In Sketchup, I downloaded a trailer base (because I knew I wanted a roughly 4X8 bed on the trailer.
I also knew I wanted to just put a couple sheets of 3/4″ plywood as a floor and building base for the rest of the trailer.
When I build another one (a larger, “canned ham” type), I will be building it with a 2X4 framed floor and use the plywood as a subfloor, but that isn’t really diminishing the stability of this one, because it is attached to solid steel.
