The 105 Series was made because of strong demand from Australia and Africa. The 100 alone could not pass durability demands in those markets.
The reason they don't have a 200 Series solid axle truck is probably because it has a much better ifs system and buyers are getting 70 wagons for heavy duty use. Just a guess.
