Mostly minor progress on the truck so far. I built a fairing for the roof rack out of 1/4" lexan and some foundation straps from Home Depot. My first attempt didn't have enough support on the lexan, so at speeds from ~20 mph to 70 mph it flapped in the wind and hit the roof. Once I put more brackets on it for additional support, it was a night and day difference and I can now hear myself think while I'm driving again. Just need to take it back off to paint it now...
In the process of gathering information to do a 6 month review of the softopper, I decided to run a quick and dirty test to see how it affected fuel economy. I've been wondering for a while now why I'm getting city MPG on the highway when Toyota advertises 24 mpg, and I finally figured out why.

This was with the topper up, normal (for me) highway driving.

And this is with the topper folded down against the back of the cab. Same route, same driving, and the only thing I changed was the topper being folded down. I will most likely be getting a boot cover for the summer months, but with how the topper reacts to the cold it will most likely stay up for the winter. Hope someone finds this information useful.
