I am going to call the dealer today and ask them about installing the heavier brackets before pick up. Not concerned about the time frame to do it....just want it done. If they decline I may forfeit the $2K deposit.....my bad....and expensive lesson.
My inclination was to originally go with an AF 29-5K. I think they may be better built but the important half of my relationship did not like the layout....not enough storage.
Just no way to win.
