Well two of us did this one with a tractor and end-loader and two ladders. It wasn't bad, but I doubt if I ever have to install another. The top rail was indeed the hardest part. Stringing the cables and hose wasn't bad at all.
There is no way you could put this one all together on the floor then just stand it up. It would have hit my lights. We had to maneuver it around in between the lights at an angle before standing each post up straight.
I'm sure you know what you're doing, but this was our first and we did it the way we thought we had to and striving to be safe.
