Yes, plenty of 24M still comin down under.
IMO Caterpillar need to build a 20M grader and fill the gap, i have been saying this for a while and i hear there is movement on it.
16,s are just a tad small nowadays and 24,s can certainly be considered to big in some cases but usually the $$ rule on the decision of what to purchase.
Cat have made a bit of an art of creating new markets by coming out with a monster and then years later filling the gap, 793 to 797, then fill in with the 795, D9H to D10 to an extent, 992 to 994, then fill in with the 993
