@Reet - I did a slight variation because of having an EV-1 in there as well. Used 1 1/2 foam on part of the lid. The pedal was in the way of closing, so I used 1.5" foam behind the unit to keep it from sliding and 1.5" and the std foam it came with for the top. I added a little behind the EV-1 to keep that from sliding.
I used to use a folding hand cart and with the build in wheels, I won't need that. Granted, it probably won't fir everything I need to bring, but it will keep the unit safe during transport.
