Prodigy Setting

Just purchased another TV and installed a prodigy BC. The other unit was a draw-tite, on a Ford Freestar minivan which I did not like, because of the jerking and always having to set the control. What do you recommend for a setting on the prodigy. I am towing a 2619 with a Ford 150, 5.4L. Leaving for a 30 day trip to California next week.
