I'm glad this thread floated back toward surface in the forums; I'm not sure I would have come across it otherwise.
We're lucky, with our trucks, to have so many mounting holes in the edge of each wheel well. I'm contemplating how to do a set of skirts on my truck, so your photos were really useful. It's good to have you back on the forum.
Edit: Oh yah, I'm doing the micro-house on wheels thing with my truck too! I'll look forward to seeing what you come up w/ for yours.
