Making the base






Sorry about the pictures being kinda small. I'm still trying to figure out this blogging business. If you click on the pictures you will see a bigger picture.


There are a few special things about this base that I would like to point out.


1) Where the bed will be located I created a frame on top of the trailer which raises that platform up the height of one 2X4. This is done because the bed extends out over the wheels and the wheels need that much clearance for the travel of the springs.


2) The rear part, where the galley will be built, steps down to rest right on top of the frame. I did this because when you are standing back at the galley you want the counter top to be about normal height so I needed to make this part as low as possible so I could fit the cooler, camp stove, etc... under that counter top and not have the counter too high to comfortbly work on.


3) You can see some black stuff painted on the inside of the wood framework. That is the black jack tar junk that is used on roofs. It is nasty sticky stuff to work with but I painted it on all of the 2X4s before I bolted them to the frame. I painted all of the exposed wood on the underside of the frame before I laid down the plywood and each peice of plywood was painted on the underside with black jack before I fastened it in place. This will waterproof the wood to prevent rot that would occur from rainwater from the road being splashed up onto the wood and into unprotected crevices. You can see that there is plastic on the floor to protect my garage floor and that the levis I used for this phase came out pretty badly. They went straight into the trash at the end of the day.


4) There is a 6-inch deep box in the floor with a trap door cover. This will be used for storage however I also have an idea, if it works out, that this may be a place to set your feet when I stack the cushions from the bed into a bench in the front. That idea remains to be worked out so for now it is extra storage space.

Preparing the trailer



The Woodsman is build on a 4X8 trailer from Harbor Freight. It is rated for 1700 lbs and I reckon the fnished teardrop will come in well under 1000 lbs so it should be plenty strong. I painted all of the parts with primer before I assembled it. The primer should help to ward off rust and also provide a good bond for the finish coat. I did not assemble the fenders because they will not be used in the build. Painting and assembling the trailer took one Saturday.

Starting a New Project









Hi All,
I thought it would be nice to create a build log on the internet as I build my teardrop trailer so that people can follow along if they are interested. I hope you enjoy it. Feel free to post a comment if you have an idea, question, or just want to give me a word of encouragement or tell me about something you learned while doing a similar project that may help me.

Why a teardrop trailer? Cheri and I like to get out in the woods for little overnight campouts. Sit around a campfire, maybe take nature walk in the morning. We live in the beautiful state of Utah with abundant camping nearby. For some time now I have been thinking of upgrading from tenting to a camp trailer to make the preparation easier and sleeping a little more comfortable. To be honest, the biggest motivation for me to have a camp trailer is not having to haul all my camping gear up from the basement and load it into the car. I'm hoping that having the trailer parked and ready to go all summer will entice us to get away more often.

The idea of a teardrop appeals to me because of the simplicity. You’ve got a place to sleep and cook that’s small, cheap, and easy to tow.

About the design. I spent a lot of time sketching preliminary designs before settling on the basic design in the drawings above which I call the “Woodsman”. Here’s a list of features that are important to me and which led to this particular design:

1) Ability to sit up in the trailer. Most teardrop designs are about 4 feet high on the outside and less than that on the inside. That is plenty high for sleeping but you have to do everything lying down. The Woodsman will be about 5 ½’ high on the inside. Not quite enough room to stand but high enough to sit up straight or kneel to make it a little more comfortable when changing clothes and moving around in the cabin. Because of this requirement the Woodsman design is taller than most teardrop designs.
2) Ability to sleep two full-grown people comfortably. When we campout in a tent we put a queen size inflatable mattress down for sleeping. This is ideal for us. Most teardrop plans use a four foot wide bed because that’s the width of a sheet of plywood. A queen bed is 5 feet wide so I went with that for the width of the trailer. Cost will be driven up a bit by exceeding the 4 foot restriction of a sheet of plywood in both the width of the trailer and the height but these are both important enough to me that I am willing to spend a little more to get it right.
3) The look is also important. If I’m going to pour months of time and effort into a project like this I want people to say, “Look how cool that is!” not “How come it’s shaped like a box?” The classic retro look of the 1940’s teardrops is hard to beat so that’s the look I’m going for.

The first three items above guided the size and shape of the design. Other considerations that went into the design are below:

4) I have a budget. I sold my old S-10 pickup for $3400. I would like to stay within that figure. I think I can do it but I will need to watch my pennies and I’m sure the budget will influence many of my choices.
5) Insulation. I plan to insulate the entire sleeping compartment. I am hoping that a well insulated compartment can be kept comfortably warm with only body heat on cool summer nights in the mountains. I don't have plans to do any winter camping.
6) Ventilation. A ceiling vent with a built-in fan should be able to pull air in through the side windows and keep the compartment from turning into an oven when the sun hits it. Keeping cool in the daytime is another motivation for thoroughly insulating the sleeping compartment.
7) Electric lighting inside and out, including the galley and a light above the door on the exterior.
8) Circuitry to connect a 110 power cord which will charge the batteries, run the 12V system, and also power one or two 110V convenience outlets.
9) Entertainment center. Even when we camp out in a tent we bring along a portable DVD player or iPad with a movie loaded up. I’ve gotta have a stereo system and some kind of movie player.
10) Space in the galley for the following items to be securely stored:
a. Propane cook stove
b. Propane lantern
c. Spare cylinders of propane
d. Cooler
e. Cooking and eating utensils
f. Pots, pans, mixing bowls
g. Plates, cups, bowls, napkins
h. A few cans and packages of non-perishable food such as chili and pasta.
i. Soaps, dish towels, rags
11) Doors on both sides. This is a comfort thing. If I feel like laying down for a nap in the daytime it will be nice to open both doors and take advantage of the mountain breezes.

The design. I have to confess that, although there are some unique features of this design, much of it consists of ideas that I have borrowed from other teardrop designs that I have seen. Many thanks to all my predecessors who have shared their designs on the internet!



I am making a 3D drawing of the design. It's not finished yet but I posted a couple of views at the begining of this blog to give the general idea. For creating the drawing I use Google’s sketchup software. It’s free ( - : Some nice-to-have features are missing from the free version but I can get everything done that I need to do. There are several advantages to making the 3D drawing before you start to build. One advantage is visualization. You get to see how it will look and where everything goes, and unlike the real thing, you can tweak it as you go along.
