The truck tows the trailer well in 3rd gear on the highway at 2400 - 2500rpm. Never downshifts unless it's a very steep hill.
Would going to a 4.10 from the 3.42 be worthwhile? It would move my cruise rpm up to 3000 in 3rd which seems unnecessarily high, but I assume would make accelerating a bit better.
I would aim for 2500 - 2700 in OD. Not sure of your transmission ratios but that would probably put you in 4.56 or 4.88 ratio.
