I'm currently leaning towards the Eckla cart - carrying capacity is about 170 pounds, and it has big tires for all-terrain.
Currently planning a good transport system - which includes a system of cases that can be stacked one on top of the other, including the sandbags.
I'll probably have the two generators on the bottom, and then the case with heads and pocketwizards, and the head extension cord tucked behind.
Just found a great brand of cases that look better to me than the Pelican cases, with very adjustable interiors. That's only for the equipment that can actually be transported together. Other parts of the equipment has to be carried on its own, like the Mola Euro or a rolling stand which weighs enough to have Atlas come to help carry it.
So I'm planning to get all equipment to the set in two runs, and have it easily set up and stowed away again.
I've had quite a chaos in the past with too many cases, bags, back packs, loose cables... which always leads to loose cannons...
