Thanks for valuable info and advice.
In answer to lubing the ball... Yes, I have always greased it. Based upon some of you here I will lube with the Vaseline that's in TT medicine cabinet. I also will chock TT wheels and pull truck forward a hair to take pressure of the locking mechanism before beginning the whole process.
Just traded in my 1/2 ton F-150 for the 3/4 ton diesel in my signature. Yesterday was 1st tow with that TV. We fairly flew over Snoqualmie Pass. Love it. Now if we can get this TT situation fixed life will be even easier.
