Update:
! - SUCCESS - !
a few notes:
The first challenge has resolved by itself, the wight of the RV has push the ball deeper and now I can slide the bottom pin in and out without a problem.
look for Andersen videos on YouTube (as they do address that).
I have found the Jayco 184BH frame to be very soft, as I tight the brackets I have notice that the frame got slightly squashed on the sides, also the set screw dig really well
in to the frame
(I didn't drill any holes, and only did 2 - 2.5 turns per set screw, I also considering welding it in the future)
a few more notes:
1. I used my Jeep for the WDH install, the plan is to tow the RV with my dad pickup truck for the time been, until I get my own truck... hopefully next year.
2. I know that many people are towing my RV model with a mini vans and other v6 3500lb max tow rating vehicles.
I was always wondering how close or over are they, so for educational purposes only I will tow the RV to the nearest CAT scale (with camping gear and everything) as I am dying to know what the real numbers are.
