Rotated 45 degrees it may have been over 8' 6" but up on the truck bed it could more likely be over height. Even if size was an issue (and I don't think so) any savy truck driver would load it as low as possible. What it's mounted on could be a limiting factor as well. I personally would have put it more centered on the truck trailer. The fact that they used a low boy trailer indicates it brobably would have been over height on a standard trailer. Talk'in about this takes me back. Most all the trucks I drove were flat beds.
