Step 1: Buying the utility trailer - piecing it together.
Per the plans I was using I bought a 4x8 utility trailer from Harbor Freight. It has a weight capacity of 1800 lbs. Which should be plenty for my tr...
Step 2: Building the subfloor - preparing plywood floor
I bought some 2x2s to build a subfloor that rests on the trailer. The purpose here isnt really structural, but more to create frame that a floor can...
At this stage, I'm working on the 4x8 ply sheet that will be the actual floor. Note, the trailer itself is 4x8. To accomodate the walls that I will bu...
These trailers are small, even tiny. So any addtional cargo area helps. A frequent addition is a cargo compartment nestled under the floor, between ...
Once the subfloor frame is complete and the ply floor is complete, you can glue and screw the thing together. I used construction adhesive and deckin...
Once the tar has congealed after a day or two, then its time to insulate. Why insulate? Depending on your climate, you can have serious condensation i...
In my case I primed the floor, screwed it all together, and bolted it to the frame. One side note - there will be a gap between the metal crosspeices...
I knew the specs on this trailer were for a max capacity of 1800 lbs or so. I guessed my finished trailer would be about half that. So I decided to t...
Next add on the tongue. I new my design would not be anywhere close to the max capacity of the trailer (1800 lbs or so). So I just used the stock to...
These stands come in a variety of shapes and sizes. I liked these because they are attached to the trailer. You just have to remember to retract the...
Now we can set aside the trailer for a while now and focus on the walls. I sandwiched two 1/2inch plywood sheets together and screwed in several plac...
Inside the trailer, folks frequently have a variety of shelves and cabinetry. Not to mention there is a door (typically on each side) as well. I moc...
Step 19: Quirky Profile - The discussion and the solution
The standard plans use 4x8 sheets of ply as the basic size of the floor and walls. But that means you sacrifice a little floor space. I also felt th...
Step 21: Finish the Sandwich: the inside surface of the walls
I decided to use 5MM plywood as the inside layer of the wall sandwich (1/2 ply, 1x3 spars & insulation, 5MM ply). Again I screwed the two pieces toge...
I wanted to have some sort of lighting inside the cabinet. I struck upon adding LEDs to the overhead crosspiece, with a switch to turn them on. I mad...
Working off the ends of the sidewall sammich. I began to add crosspieces and more sections of the 5MM ply and insulation to build up the walls. I us...
Step 28: Tripled Spar for Hurricane Hinge; Battery Box
Now that I have the 'attic' all built, I can put in a heavy duty spar. This is a tripled-up piece of wood that will be the base for the hurricane hi...
This is essentially the ceiling inside the trailer. I used more 5mm plywood, painted with the poly stain mix. I was worried about bending the ply af...
With the headliner in, the vent and ceiling light installed, the insulation can be finished and the wiring can move along. I ran the wiring through ...
So it sounds weird but I wanted a bookshelf in my cubbie. Of course a bookshelf in a moving vehicle presents some concerns. So I wanted to create a ...
This was kind of tricky. I actually glued the front half down first, with some aluminum nails at key points. Once the glue cured, then I glued down ...
Now that outer roof is down, we can attach body side of hurricane hinge. I special ordered this hinge online. It comes in a beefly plastic tube, so ...
I'm using a special water-resistant type hinge for the galley hatch. Its designed so that water cannot run inside through the hinge. Available only ...
Once the hatch is built and the roof is attached and cured. And you have the hole cut for the vent fan (although you could probably wait and do at a l...
Now it is time to turn attention to the side doors. You should already have some door blanks cut from when you made the openings in the side wall. Y...
Once the opening was all trimmed out AND the door was all trimmed out, we could fit it together and see where to attach the hinge. I used a stainless...
I used a vent that is smaller than the standard size. It did NOT come with a fans. So I used some simple PC puck fans and small pieces of metal angl...
So now that it's painted, the windows are on, the doors reattached... it's time to take some pics. There is still some work to do, but we can get thi...
