OP...
I have no affiliation with this next recommendation...
Andy at CanAm RV is THE expert on these combos... One great portal into his thought process on hitching, WD, and Receiver reinforcement was an interview he did on the VAP (Vintage Airstream Podcast) back in 2013.
Its an hour long and it cost $0.99. IMHO... its well worth the $$
Here is the link
Andy InterviewGood Luck!
PS... I am towing "near max" with my Minivan and my AWESOM POP UP... I use WD, brake controller, and the combo is GREAT. Handles well, is rock solid, and I have no real desire to change TV's.
Thanks!
