I have the 6.2/3.73, and tow in 5th gear most of the time. I run 60-62 mph at about 2000rpm. I get 8-10 mpg depending on wind. I am pulling around 9500#s.

you got the right plan. Glad to see you did not get locked into the ozone layer.
Getting back to your test pull. Here is a thought. I have looked as at charts on engine rpm and speed with the 3.73 compared to the 4.30. So your 3.73 in 5th will be very close to the 4.30 in 6th. So if you are on the ragged edge of maintaining 6th on the flat land, consider just running it in 5th.
Do a little experimenting.
Don't forget to post back after the test drive.
