For what it is worth, a tomato truck carries 50,000lbs of tomatoes from the field to a processor. Supply chains are complex, but refrigerated semis can carry a similar load of processed vegetables.
Edit: got curious and spent 2 minutes to do the google. The unvetted answer is aprox. 10%
A semi can run ~1500 mi on 200 gallons @7.5 mi/gallon and a trailer refrigerator uses about 10 gallons/day
