Introduction: Teardrop Trailer
Each step is one day.
Please visit my website: http://www.teardropdiy.com.
First of all, my day job is software programmer. This is my first build. I have basic knowledge of wood working and I have some tools. The build is going to take a while (a month? two?). I only have time to work on it from 8PM until I go to sleep (about 3 hours) and in weekends when we have nothing else planed.
My plan is to keep the price under $1500 $2000. You can buy already made teardrops for $4000-$11000.
My Hyundai Sonata can pull a trailer of 1000lb max. My plan is to make the teardrop be under 700lb with all the equipment inside.
The only size of plywood that I can bring home is 4'x8', so everything that's made of plywood should fit in that size.
Here is how the side wall of the trailer should look like.
A list of parts with links from where I got them:
- Trailer. I'm going to use the 4x8 Super Duty Utility Trailer from Harbor Freight Tools to built the teardrop on. On the time of creation of the website, the trailer was on sale for $350. I got in mail a %20 off coupon and that made the price $280. Note: If 4' wide is not wide enough for you, you can use this trailer . It's a little more expensive, but 1 foot wider.
- Doors. You can build your own door. I won't. I'm afraid that I'm not going to be able to make it water tight, so I'm going to use already-built doors. I was lucky enough to find two brand new doors for $230 both, from someone who builds teardrop as a business. Here is his business website, he sells anything you need for a teardrop, including kits and custom made teardrops ( http://www.dnmteardroptrailers.com/ ). Note: You can use only one door on one side, and a window on the other side. I got two doors because they were cheap and I won't have to step over my wife if I have to pee at night. You also can get them from eBay .
- Vent. I need a vent to put on the top of the trailer. I need one that's able to move lots of air (the door windows won't open on my doors). From my research the best vent is " Fan-Tastic Fan ". I already ordered one from eBay for $120.
- Hatch hindge. For the big door that lifts open at the back of the trailer. This should be water proof. I'm using a " Hurricane Hinge ". Already ordered from eBay for $71. You also can get it from here .
- Porch Lights. I need two porch lights to install above the doors. Ordered 3 from eBay for $63. 12V LED.
- Dome Light. I also need some dome light for the inside the teardrop. Already ordered from eBay for $17.99. 12V LED.
- Water pump. The best pump I found is the 12V Whale GP1352 submersible water pump. You can buy it from eBay for as low as $25.
- Hatch handles. Got those from eBay .
- Aluminum. I called around all the sheet metal places that I found in my area until I got the best price. I got mine from http://www.ircalum.com , they are from Portland Oregon.
- Aluminum Molding. Go here and click "Online parts catalog" then go to "Moldings"
- Sink/Stove combo. Got it from here .
Tools I use:
- Box cutter
- Framing square
- Wrenches. Big ones. You'll need for the trailer 16mm, 17mm, 18mm wrenches (I suppose this depends on what brand of trailer you are using)
- Wireless drill
- Chop saw
- Table saw
- Belt sander

Step 1: Day 1 - February 8th 2012
Feel free to click on the pictures to see them in full size for more details.
The trailer box opened. Looks small.
Lots of screws and parts.
Hmm. All the trailer parts look the same.
The trailer starting to get shape .
I had to go buy some more wranches, mine are too small. Enough for tonight.
I woke up in the morning with muscle pain everywhere. I discovered some muscle that I didn't know I had. Crawling on the floor trying to put a trailer together is not easy :-)
I'll have to paint the trailer frame black. Red with aluminum gray won't go nice.
Step 2: Day 2 - February 9th 2012
Step 3: Day 3 - February 10th 2012
Step 4: Day 4 - February 11th 2012
Step 5: Day 5 - February 12th 2012
Step 6: Day 6 - February 13th 2012
Step 7: Day 7 - February 15th 2012
- Put the wood frame on top of the trailer, clamped to stay in place
- Tap it with a hammer where the frame rests on top of bolt heads that keep the trailer together (this will mark where the trailer's bolts are and you'll need to carve some spaces so that the frame will lay flat on the trailer)
- Use a 1" spade bit to make space in the wood frame for the bolt heads.
Warning: do not try to cut both walls in the same time, stacked together. Doest't work. One by one, slowly, works the best ;-)
Step 8: Day 8 - February 16th 2012
- The exterior walls are going to be the 1/2 plywood
- Hard foam insulation
- The 5mm plywood on the interior.

Step 25: Day 25 - March 24th 2012
Step 26: Day 26 - March 29th 2012
To install the molding and be able to bend it around the curves of the teardrop, I'll need to soften the aluminum first (annealing). This is done by heating the aluminum to very high temperature and then letting it cool down slow. Aluminum doesn't turn orange when hot like steel, so you'll have to decide when is hot enough without melting it.
Done for today!
Step 27: Day 27 - April 7th 2012

Step 32: The Kitchen
The stove is connected to a propane cylinder.
I saw some comments proposing solutions on how to charge the battery. Here are two ways you can charge the battery with the towing vehicle while driving.
Who knew that there are Teardrop Gatherings and Teardrop-Friendly Events... here is a list I found:
My wife said that now I proved myself so I should start remodeling the kitchen. :-)
"Let no good deed go unpunished."
Thank you for reading my build log and ... go make some sawdust!
Post scriptum 2:
I added another page with pictures from our first trip to "TearJerkers Birthday Bash 2012, celebrating 15 years of TearJerkers" in Grants Pass, Oregon. It was lots of fun. Check it out.
