DIY Squaredrop Camping Trailer Build
Design and build time: 4
months. Total cost: just under $5,000
We
love to camp on our motorcycles and also with the
car, where we can then take our dog. But being in
Oregon, the good weather season is fairly short and
tent camping in the rain isn't much fun.
After canceling yet another camping weekend due to
heavy rain, I decided we needed a camper. While we
would love a Sprinter Van, it's out of our price
range. We also have only a small car, so towing a
large camping trailer is out of the question.
I looked into teardrop camping trailers and we liked
the concept. But looking closer at teardrop camping
trailers, I saw a lot of things I didn't like: While
the teardrop shape gives it a low wind resistance,
it greatly reduces the usable space inside. The
galley cover protects the actual galley from rain,
but you'll be standing in the rain while cooking.
The price for an off-the-shelf teardrop camper is
also quite high. Building a teardrop yourself (DIY)
is complicated due to the rounded shape.
Then I saw images of square drop (squaredrop)
camping trailers and immediately knew that this was
the solution I had been looking for.
The build took place from November through March in
my unheated garage. Due to very low temperatures I
couldn't work on some evenings or weekends,
otherwise I could probably have built it in 3
months. Another time-consuming task was the constant
moving around of tools and material in my garage,
which is clearly too small for a job like this.
There are plenty of YouTube videos about
camping-trailer builds, but I personally like to
read a description and take my time look at photos,
instead of constantly pausing a video and rewinding
it. That's why I created these pages.
In the the descriptions below and on the following
pages, I describe the reasoning behind my design and
the DIY building process, and I link to some
products that I've used that I think will make it
easier for you. I'm not paid or sponsored by any of
these products, but I may receive a few cents when
you use the link to purchase an item.
I recommend getting Amazon Prime, at least the
30-day trial, as you will be ordering a lot of
stuff. It comes out a lot cheaper with Prime and
gets delivered quicker.
The trailer was on purpose built without AC, but we
found out that we need a heat source if we don't
have shore power and propane heaters seemed a bit
sketchy. Therefore I built a portable
diesel heater, which we can run off our
battery. I wrote how to build one on
these pages.

I'm
a mechanical engineer and have access to
Solidworks CAD software, which I used to play
around with ideas and then to design the
square drop camping trailer.
I designed the camper around my 4'x8' utility
trailer from Harbor Freight, but made it a
little wider for some extra room inside, so
that the outside would be 5 feet wide. The
living area is 8 feet long, with an additional
18" length for the galley (kitchen). |

Some
use steel tubing or aluminum tubing, but I
suck at welding and I wanted to keep cost and
weight down, so I went with wood. I used
2"x2"s (actual dimension 1.5"x1.5") and
marine-grade plywood from Home Depot.
For the bottom and back wall I used 1/2"
plywood, 1/4" for the outside skin and 1/8"
for the inside skin. The vertical beams don't
need bracing, as the glued and screwed on skin
will give it the needed rigidity. |

I
couldn't get 5'x10' sheets of plywood, so I
had to go with 4'x8' sheets and carefully glue
and seal any seams it created. I recommend
using Titebond
III Waterproof Wood Glue.
The plywood base was then insulated with 1.5"
of foam insulation and covered again with
plywood. Regular Styrofoam insulation is good
enough for this and much cheaper than the pink
foam boards. |

I
cut a bunch of 2"x2"s to size according to my
plans and screwed them to the base, using deck
screws for additional corrosion resistance in
the still somewhat wet wood from Home Depot.
This work goes rather quickly and it's
satisfying that you can immediately see the
camper taking shape. But don't frame the roof
yet.
I consider the Kreg Pocket Hole Jig
essential for this build. |
