This has all been very helpful, My FWC Eagle never comes off my truck, so using the jack brackets might be the best idea. I emailed Rocky Mountain FWC to see if they have any ideas. The frame photos were great, I didn't know that the FWC had a aluminum rail all around the top of the sides. But I was trying to figure out how to keep the roof clamps functional, the aluminum posts that NWcamper designed solve that problem
With regards to wind, rain, the Foxwing has poles and stakes, so it would work in a gentle rain and low wind, if it's really blowing, I'm gonna stay inside the FWC, LOL. I like the self-supporting feature of the alu cab awning, except the price is up there with the bat wing awning. Foxwing is around $850. I'm usually not in that much of a hurry to setup camp and spending a few minutes with poles and stakes/sand bags wouldn't bother me.
We just finished 9 nights camping at Big Bend Ranch State Park in Texas in their 4WD backcountry campsites and could have used more shade than the camper itself generated from 2-4pm. We tried to finish hiking before the hottest part of the day.
We have reservations for the White Rim Trail in May and I really think I need something for shade. I'll keep everyone up to date with my progress.
Thanks again to everyone, if anyone else has any ideas, please post.
