Bob, you said that it's not how much you have 'dialed' in it's how stiff the WD bars are.
My TV is a 2018 GMC 1500
crew cab, AS 2019 27 ft twin Globetrotter. My WD hitch is a Blue Ox Pro 1500
lb bars. Most AS dealer recommend using 1000 lbs bars.
I have not put my loaded rig on a scale, I know I should and will.
Until I do, my question is, I normally tie down my WD using 7 chain links, which gives the bars a slight curve. I would like to tie down 8 chain links, which give me a more stability. Will dialing down 8 chain links damage my AS?
