Doorsill

The big sliding door needed to be supported out beyond the edge of the trailer, so we put in a metal sill:


Here you can see how it hangs over the edge of the trailer. There is a piece of light-colored foam on the ground in the background, that makes it hard to see how the red part goes:


It stuck out beyond the wall, so I made a little piece to support the flashing tape. The two little flanges on the left-hand side go under the red sill, to fill the gap behind the red sill, so the tape has something to sit on:


You can't see where it goes under the lip of the red metal, but here is it installed:


I'll put down flashing tape, and then protect it from footsteps with another piece of metal. Here I am forming and installing that exposed door sill. I need it to cover the tape that steps around the metal in the corner shown above.



The flange is bent:



Have the step, just need to bend the upstanding flange by my left thumb:

One corner, neat and square:

Windows

We have been putting in windows, but not posting pictures, so here are some:
This window was designed to be vertical, but we are installing it on it's side. I think it work.


Here we are framing out the curved window:



Here we are preparing to put in a door:



Here is the north window, installed (but without flashing tape yet):



Here is the north window from the inside:

we got rain before I put on the flashing tape, and water came in. I guess caulking the flange wasn't good enough. I was always planning on using the tape, but I'm hoping that the flashing tape is just another level of safety, and isn't really needed...but I guess the caulk wasn't good enough. I'll probably try to fix the caulk, and then tape it.

Here is the door sill after I've bolted it down, and painted it.

See, the door assembly is thicker than the wall, so I want it to hang out beyond the trailer a bit, but the threshold of the sliding door needs support, if people are walking on the edge. So, I got a scrap of metal angle, and bolted it to the metal trailer frame, though the subfloor. I painted the bolts and nuts. The bolt heads will stick up out of the red sill, and into a groove in the bottom of the aluminum door frame, which will help keep it all in place.
