So, adding a working door handle to the Nookery took all afternoon. Be forewarned, 2" foam doors make for some interesting adjustments.

I caught the handle on clearance for $7, it's a nice brushed nickle metal screen door handle. It had all the required parts and even had several sizes of door keys. I thought I was gold. Nope. But more on that later. I knew I had to add a hard surface to mount the handle so I decided to work from the inside of the door. That way the outer skin and some of the foam would not be disturbed. I had to think about how everything would fit because the face frame adds 5/8" to the overall door shut and lock equation. I finally decided to glue two pieces of wood together to make the correct depth. I cut one piece of the wood and used it to trace an outline of where I wanted the door handle to be.

Then I used my box knife and a 1/4" chisel to remove the skin and most, but not all of the foam.

Then I test fit the wood piece. Score! Looked great. Tight enough, I had to work to get it out.

I removed it so I could glue the other piece to it. Lots of TBII and some clamps and I let things dry while I ran around to get the 1/2" drill bit and such. Found a set of drill bits on clearance at Sears - $7 and it had a bonus bit that just happened to be 1/2". I am happy camper, so I head home. Once the glue dried (it's 93 today, so it was fast), I test fit the piece again. Then I used a garnish piece to mark the holes. Then I clamped the entire arrangement, with another piece of wood under the door piece to the trailer tongue and drilled those holes.

Well, I'm excited now, because so far I've only had one HD run for this project. That changed. I was in the middle of dry fitting everything when I realized the door key and the bolt were going to be too short.

Off to the HD for trip #2. It took 4 hardware stores. My neighborhood mom and pop store had the correct size alum. square rod for under $4. I'm afraid the gentleman who helped me was a bit put off I didn't own a vice or grinder.

He kindly cut the alum. to the correct size and beveled the edges. And it was a perfect fit!
The bolts took a bit more looking and I ended up finding them at the Lowes right down the street from my house. Figures. Anyhow, so I head home having added a measly $1.40 to the door knob project cost.
After a bit of convincing, the door handle is on and shuts and locks!

Total door handle cost:
Handle $7
New Key $4
Drill Bit $7
Bolts $1.40
Total: $19.40, well really just $12.40, if I don't count the bits.
Now, I will need to take it all apart and actually finish the wood and glue it into the door. That's for another day.
Bonus is the mock up of the graphic for the trailer. It will most likely be in the HF red. What do you all think?
