Used the same actionpack Rubbermaid container as in the Sacramento to Kona page.
I had to keep it under 50 pounds to avoid paying extra.
The container just had the base unit and the two fenders ... no rubber mat, no batteries and the total weight was 53 pounds. (didn't have to pay extra)
Had to poke a hole in the side of the container since the tire bolts were putting an uncomfortable amount of
pressure on the sides of the container. The bolt is still protected beause the container is beveled in a little bit so nothing will bang into it.
