at least with GM diesels, if you have cruise, and/or tow/haul on and/or exhaust brake AND the computer detects slip between the front and drive wheels it will almost instantly kick off cruise, and/or tow/haul and/or exhaust brake.
On older vehicles, using cruise and other functions could get you in trouble if wheels start to spin or slip because the offending function wouldn't kick off.
another thing I found interesting is that on my duramax once going downhill I shifted to neutral to see how fast I would pick up speed. What happened next was a suprise. Engine rpm STAYED THE SAME! and then went up as speed increased,it did NOT go down to idle RPM, even though the engine was indeed in neutral. shifting back to drive was as smooth as a babies butt.
Personally, other than ice or snow I use cruise, tow/haul/ exhaust brake when needed regarless of rain or not.
