Hey
In regards to the cab over box. It worked well for years. I stored a portable solar panel in it with a thermorest as a cushion. The wind foil works well too. I sold the Tacoma and bought a Colorado diesel. So I removed the box leaving the air foil on and I am installing an aluminum side in for 3, 2 gallon diesel cans. I can't seem to figure out how to send a photon in a PM so if you send me your email In a PM I could send a few photos of how it was and will be.
