I am not trading off my Dart! Need a new truck.

I have a 2013 Hemi Ram. I love the looks, performance, interior, everything. What I hate is it has tire shake at 55 and up. Changes with different roads. I think it's a bad tire or a rotor. But I can't get it resolved because the dealers suck. Keep feeding me BS about how it's the balance. Then I need weight in the bed. That makes it worse. Got me for $500 so far with tire rotation, balancing twice. Once road force. Alignment. Then I get the I don't feel anything. Very frustrating. All vehicles have issues. It's the bastards at the dealerships. Had the same thing with the navigation system. Would just shut off for no reason. They told me it's cause I have the better system.??? Ever since I got the security update, I haven't had any more navigation issues.
