Tow/Haul Mode?
What governs your use of tow/haul mode while towing? Does increasing horsepower reduce the need for using tow/haul mode?

The 2006 Ram has two T/H modes. IIRC, one locks out 4th and the other allows it but changes shift strategies.
Correct.
03-04 was a lockout of 4th gear.
04.5-05 was a T/H; altering the lockup timing of the torque converter clutch. It still allows use of 4th gear. A dealer flash is available to convert to the older style 4th gear lockout.
06-07 has both the T/H and the ability to lockout 4th, because of the added memory of the ECM.
