Can't add Maritime Escape Pod

[assaultdoor]

Using MML 0.47.4 on OS X, I can't seem to add a Maritime Escape Pod to a vehicle. I can find a Maritime Life Boat, but not a pod. If I edit the blk by hand, MML recognizes the Maritime Escape Pod, but claims it only weighs one ton. It should be seven tons.
