actually my rather broad statement was specifically made to make a simple distinction between the two

a forklift is designed to do a specific job as the tug also is designed to do a specific job. Certain specifications between the two are so far apart on the scale they can hardly be compared as anything other than what they are.

I'm still wondering where kariat's comment about 'industrial' came into play. We all know either machine would most likely be industrial by design. ;o)
