I'll use drive and tow mode on back roads. It will stay in gear longer before upshifting, and it firms up the shifts. problem with drive however, is it will eventually look to go to 6th gear which is to high of a gear for any towing duty. On the interstate I'll manually select 5th. If I'm pulling a hill and it won't stay in 5th, i'll select 4th. I haven't found a interstate grade I couldn't pull in 4th. The torque converter locks up in 4th, 5th and 6th, however it won't lock in 4th if you have the shifter in 5th, 6th or drive.
