I have put long stuff in my truck many times, plywood, drywall, framing lumber, etc. 10' lumber will fit if you don't mind it up on the center speaker (put some padding on it), but I was always nervous about doing that, afraid it would bend, so I just leave it sticking out, put the upper tailgate down on it. 16' long pieces won't fit, but I've done it twice:
I have a piece of 2" XPS insulation board with a groove cut into it that I sit on the top of the lower tailgate, protects that edge.
You can get the annoying dinging to quit if you take a screwdriver and flip the latch in the upper gate closed. Then the truck will think it's closed. Just don't forget to unlatch it again before you close it after unloading.
