Is ridiculous! the alignment places always is guessing about the problem, for the vibration I know what is the problem in 90% of the cases and you can fixed whit out spend any money.
Did u ever solve the vibration problem on your truck? Im having that problem now, so im going to troubleshoot. With new wheels and tires maybe your alignment or imbalance at the brake drums cudve been it(?) Let us know what u ended up doing? Thanks
