Based on my own experience moving my 9600 with the help of my son, my guess is that without the carriage frame it was less than 100 pounds, the frame is removed with 2 or 4 screws, have a flat and a Phillips screwdriver with you.
Lock the print head, it should be a bracket that comes with the printer when is delivered new, very easy to install.
Try not to incline it much, we managed to keep it almost horizontal most of the time and no ink was spilled.
Remove the cartriges.
You may find two plastic tabs protruding from the bottom, I think to help position the printer on the frame, make sure to make room for them when you place it on your truck, we broke one, didn't affected how the printer works.
Pay
Drive away
Remember to remove the print head locking bracket or the tape you used to lock it in place if bracket was missing
Print like its no tomorrow

We placed the printer on a folded bed cover and lower the tire pressure on the rear tires to minimize road shock
