The Ram is no worse than the others, if you find one that has been taken care of and not owned a want-2-be kid racer you will be fine.
Some 4X4 trucks had the so called death wobble, I work for FCA and do not know of any truck having it that were not running over sized tires and wheels. Makes me think that the trucks were at the upper limits of the suspension side?
FCA has fixed that, something DamnLiar should have done but didn't. You can find the same issues on Ford and GM! If Troy would carer to google "ford death wobble" there are plenty of videos for him to watch, Same goes for GM/Chevy.
They all use most of the same vendors and we have vendor sorts going on every single day, day in and day out. Just like at Ford, GM, Honda, Toyota and every other car company!
