So I have taken a few pictures after the good rain we had yesterday and last night. Remember these are prototypes and they are in process.
The first pictures are of the rear bunk and how the awning looks from outside and above. You can see how the awning attaches. It uses the same type of track system the main trailer awning uses. This track is vinyl and is screwed and siliconed to the trailer. To put the awning up, you just open the bunk, unzip the rear window and screen, and walk out onto the bunk platform. The awning slides into that track in just a few seconds.
The awning frame or pole is in 4 pieces for easy storage and assembly. The 2 straight poles screw into the bunk brackets in 4 turns, then the bent frame is slid into the awning loops, then the poles slide together.
The last pictures show the attachment point of the side flap of the awning to the trailer. This is a simple D-ring screwed and siliconed to the trailer. The strap here does not see much load and is only to keep the awning from Flapping around (I may change this to a Bungee so the awning cant be over tightened). The main straps that do the work are around front of the awning and pull the poles down, which tighten the awning. Which has a (not shown) simple bracket on the bunk door that the webbing strap attaches to so the awning can be drawn tight.
And the last picture shows the awning frame attachment bracket. This has a large nut on the end where the poles attach. This bracket slides so when the bunk is closed, the bracket does not interfere with the closing latch mechanism.
All in all I love it so far. I was in the trailer in the rain last night admiring how the bunk actually didn't seem as loud when the rain was coming down in buckets. Then I proceeded to open the windows on all sides about 6-8" to let a breeze come through while it rained. I just smiled to think of all the times i could have used that when it was raining before. I think these will be great for me and if I can finish them this weekend, I cant wait to step back and admire the looks too.
