Hi Kevan, I would suggest lifting the lever so the half nut is not engaged and using string or rubber bands secure the carriage so that it cannot move. I would then place it in a large box with bubble wrap around the 50 to protect it when you are driving and place it in the vehicle so it will not move about.
