I am picking up my 2020 Limited tomorrow. I am coming from an F150. I am looking to install the 4" BDS kit with the Helliwig rear sway bar. The caveat is that I tow a 9000 lb boat several times a year. Would you go 20x9 +1 or 20x10 -18? I plan to go 35x12.50 ridge grapplers if it won't affect my towing too much. Thoughts?
