Mine rarely downshifts from 6th unless I'm pulling a pretty steep incline with the cruise engaged. It may drop a couple MPH on a hill but cruise and 6th stay engaged. Only pulling about 12K 5th wheel toy hauler @65mph so its not working hard at all.
Big difference between 4.10s and 3.42's.
Agreed. My 4.30's allow me tow in sixth gear and it will shift down to fifth on inclines. The steepest grades will usually pull in fourth unless a lower speed limit warrants a lower gear. This is on a detuned chassis cab typically over 14K lbs GVW and 22K lbs GCW but it will be over 16K lbs GVW and 24K lbs GCW starting this spring and I don't expect much difference.
