Question: what is the difference between h-20 and hs-20 loading?
Answer: The only difference in these two vehicles is that the “HS20” truck has an additional 32,000-pound axle located under the trailer, which is separated by a minimum distance of 14' – for a total load of 72,000 pounds. An “H20” truck only has one axle under the trailer and a total load of 40,000 pounds.
