I would imagine the cost to change gears from 3.73 to 4.3 would be substantial, and through the roof if it is a 4 X 4.
One thing I neglected to mention when towing my roughly 11K gross weight 5th wheel using my 3.73: I 'lock out' the 6th gear. With the newer Fords with the 6.2 engine, you can determine the highest gear by just pushing a button. It just wants to shift too much between 5th and 6th gears if I don't lock out 6th.
And by doing so, I would imagine I am running similar engine RPM's as if I had a 4.3 and stayed in 6th. If I wasn't so lazy I could look up the ratio numbers and determine the accuracy of that statement, but what I know is: it works just fine for me.
