When moving any Pinny in a trailer or a ute, place two or three old tyres on the flat surface, place plastic tarp on top, wrap pinny so as to keep wind and rain out and use tie downs.

The old tyres (free from tyre places cause they are bald or $10 each at tops) act as huge rubber shock absorbers allowing all the shaking and banging to be dissipated and your pin can be transported for a mile or a thousand miles without anything shaking loose.
Transported many pins this way for drop offs n pick ups and never even had a fuse or plug wobble loose.
For legs on, pinball skates are perfect.
For moving and lifting pins the foot pump red lifters are sensational.
Machine should go into a trailer head box first up against cab or head of trailer to make the load more aero dynamic.
ie - machine head catches too much win at the back n not the front.

I like to place large rubber mat on base cause pin won't slide on rubber real well but easy to move by opening coin door at back and lift a tad whilst you slide.
Tie downs always best if you cover pinny edges in rubber carpet foam. Cheap from Bunnings.
With Coindoor facing back and at back, you can place inside legs etc only if u wrap them first in carpet rubber underlay and tape down with gaffs tape so legs don't move inside machine.

That's advice after 7 plus years of moving dozens of pinnies all over Qld and other states when I felt like going on a hunting or delivery mission.
Always take balls out of machine. Again wrap in rubber carpet underlay.
Tape keys on top of lockdown bar.

Away she goes all safe and accessible and waterproof and shockproof and thief proof while at Gas/food stations cause the pinball is covered in a blue waterproof tarp. Have fun with it !
