Do you have access to a trailer? After transporting a 150hp in my 6.5 inch f350 bed, I imagine putting two on a flatbed two axle trailer, if you can find one, would be a good way to transport. Alternatively one in your bed on the crate/tray laying down and the second on a trailer. I'd call the dealers and ask if they have any of trays, I think they unbolt the crate part? I personally wouldn't want to stack one upon the other in the back of my truck.
