Very nice!
We shouldn't park next to each other, its going to look like we each built the same thing.
I'm going with a home made awning. Tarp and some tent poles. I really like the look of yours, who makes it?
Regarding the gas springs, my suggestion is to go lighter than you think you need. I started at 4, 100 lb springs. My thought was the rack and the tent would be at least 300 lbs, and other stuff would find its way onto the rack. Couldn't get the rack back down without 4 ratchet straps. Changed to 75 lb springs, now I can do it by myself with the help of two ratchet straps.
For the telescoping posts, what did you use for lubrication? At first any rattle can lubrication would work, as it got colder and more bugs, sand, trail dust, metal shavings, etc got in there, I started using Marine Grease. It is holding up much better than the WD 40, PB Blaster, and such.
Looks great!
