From the 1986 110 Australian supplement owners handbook:-
Front axle max load
V8 1200 Isuzu 1300 6x6 1500
Rear axle(s) max load
County (wagon) 1750 Hardtop 1850 Cab/chassis 1900 6x6 4000
GVM County 2950 Hardtop 3050 Cab/chassis 3200 6x6 5500
GCM County 6950 Hardtop, cab/chassis, 6x6 7050
This shows that the maximum trailer mass for the County is 4000, but only 3850 for the cab/chassis and 1550 for the 6x6 assuming maximum GVM.
The owner's handbook (that this is a supplement to) shows maximum trailer mass of 4000 (fully braked), 3500 (overrun brakes) except for the 2.5 diesel, which was, of course, not sold in Australia.
From this I would expect that it should be fairly easy to get the towing weight increase approved. I assume the army towing masses are reduced for offroad use.
