The floor of the "cargo box" on the four door is 60.31 inches. My cruiser is 102 inches. I don't think that your HD would fit without an extender of some kind.
The 2 door is 92 inches. In as much as it is 53 inches wide, it is very possible that you could get a cruiser onboard that "cargo box"
at an angle with the tailgate up. Or you could at least get one on with the tail gate down.
