Clutch slips less when hot?
Any ideas? for example backing up a heavy trailer, I can ride the clutch just fine when its relatively cold, but after a long tow, it kinda jerks like its not slipping like it should when lightly riding the clutch to back it up

For the same reason that a serpentine belt that's just starting to fail only squeals when it's cold, and stops slipping once it's warmed up.
Hot materials tend to get stickier than they are when cold.

When the clutch plate, pressure plate, and flywheel get hot, they all expand or get larger, or thicker in this case. Because they are larger in size (thicker) the pressure goes up due to the tighter tolerances and the clutch does not slip as much as when cold. Cold clutches slip more than hot clutches. Hope this makes sense.
