Thanks Matt. Although it will take a sharper photo of the cabin's end to see, one tip I find particularly enjoyable is the manner I replicate a fastening bolt on grab bars:
On the prototype, the horizontal bars across the end collision posts are tubing that is flattened at the ends so it can be bolted to the vertical members. I used the smallest nail set I could find that has an indent similar to a #15-17 gauge brad nail. I placed the nail set on the .028 brass wire and tapped it with a hammer, creating a raised dimple surrounded by flattened area. It now looks like there's a bolt head on the bar.
I'll have to post another closeup to see it.
