Hard to say. I think I would bottle and move them in cases rather then a 5 gallon fermentor. I just moved last month April 1st. I didn't have any fermenters or carboys full by plan, so didn't have to worry about it. In terms of space, its easier to stack two boxes of bottles on a good base rather than having you awkward fermentor splashing around.
That being said, I opened the back of the truck, the load had shifted and a 1L e-z-cap bottle rocketed out. I caught it, then another shot out. I grabbed it between my knees, and tried to get the case level again. Another bottle fell out, and smashed on the truck gate, spilling all over my knees. I reached down like a dolt and cut myself. So it was pitch black, my head was stopping the door from sliding down, beer in my left hand, blood in the other, beers between my legs, and wet pants. Typical day.
Get boxes with a lid...and pack your vehicle properly, and you will be fine. Not sure having your trub mixing up with the beer would be great so I vote bottles.
