Make sure the vehicle is big enough. You definitely don't want to go all that way and not be able to fit it in.

I would recommend using a large, thick, pvc pipe to roll it in if you have to load or unload by yourself (it makes it easier even if you have help too).

Most bolts are 5/8 or 9/16. You have to have those size wrenches.

I transport with the legs off. Bring a ziploc bag to put the bolts and keys in. Take the pinball(s) out. Put a doubled over blanket over the playfield glass, and fold the head down. Wrap it with shrink wrap.

Put cardboard down on the bed and use the pvc pipe/cardboard to slide it in.

I completely agree.
