I've read through several threads found via search. Also checked the owners manual but am still a little confused so I thought I'd ask here. It seems the owners manual recommends towing in "S" 4 to maximize engine braking efficiency. Most of the threads I looked at seemed to indicate something different. I won't be towing near max capacity regularly. My bass boat fully loaded is about 4200 lbs. Is S4 the consensus for towing or would something else be better? The lack of a tow/haul button seemed odd, just want to make sure I'm doing it right!
