If the longest dimension in city mode is still the same as the robot mode's longest dimension, you'll still have problems. If I recall, the longest dimension can only go so far, and, the girth (the addition of the other two dimensions and doubled) can only go so far as well. There may also be a total dimension limit as well (length plus girth). Check the USPS website for their size restrictions.

Yep I know. But the smaller size restictions leaves us with no other choice now with over-sized toys/items.
