That was the original plan, and might have worked better, but it was late, I was tired, and I just started shuving it into the tailgate, and it worked! Plus, the 15' foot trim pieces were really floppy. I was worried about stability and breakage if I put them up top. Nowadays, it seems trim is made from a cardboard like material that is rather fragile. I mangled a few pieces of it with the ratchet straps in the process, but 90% of it survived.
