I would not expect that to be a problem, given that you can make them wheelspin on dry bitumen in high range, it would simply take less engine torque to do that. You do need to be a little careful though, my D22 ZD30 is the usual shocker for torque moving off uphill when towing, one day I was stuck in stop start traffic uphill towing my race car and was gong to be at it for ages so I slotted it into low 4WD as I leave the hubs unlocked most of the time. I had to be pretty careful about how I got off the throttle and disengaged the clutch or the driveline unwound itself with a hell of a thump. but at least doing that I could just idle off from a standstill every time the traffic moved a bit.
