I gave all three manufacturers a chance for my dually. RAM jerked me around for 3 Mths. Ford ignored me and GM dealers as well. So I rate them all equally as crap. After 5 mths I stumbled across a GM dealer that wanted to move product and at a tremendous deal, 5 hours from, took 2 days on the phone and they kept giving me a better deal, truck delivered to my home following week. Ford finally got back to me but still didn’t listen. Local GM dealer asked why I didn’t buy from them, I told them. Anyway, first GM product for me - 2019 GMC Denali 3500 HD and I like it. ;)
