No problem. They do appear in modern, but not in D 1-2.
For me bottom line is the transfer box has all the gubbins to have CDL it’s silly to not give the owner the option to be able to use it. CDL and TC can work together.
Not been stuck with the p38 4wheel TC, but have had to use diff lock in the “slug”
also the HDC in the 322.
All have performed fine in the required environment
Not tried HDC on an icey hill though.
Think understanding how/what a system does is the first part of the battle then learning it’s limits. (Safely)
