dont worry - i wont
when i tow i roll the scales at 22.5k#. on the highway around here i use 4th gear (nv-4500) and 2150 rpm. i put a gear vendors splitter behind the 4500 cuz of how the 5th gear is attached to its shaft, the output shaft. you can not tow that heavy in 5th or it will fall apart, even if you have the best parts avail and i do. that being said i tow in 4th. around here (LA area) i use 4th under. 4th under 2150 rpm is good for 58 mph. once i get out of town i use 4th over. 4th over 2150 is good for 79 mph. and it will pull a 6% grade in 4th over @ 22.5k# like no tomorrow. how do i get up to 2150 rpm in 4th over? granny low, 2nd under, 2nd over, 3rd under, 3rd over, 4th under, 4th over. never have to go over under 1800 except when its rollin less than 3 mph and never have to go over 2500 unless i want to go over 100 mph and i have only done that once with the trailer attached.
I've run/towed with an HX40/16 and a 62/65/12 as singles and you will like the 62 WAY better then the 40 IMHO. It felt better and cooled better all-around, and you wont have to sweat huffing the S362 as they are much stronger turbo.
