So I got out for lunch today to take my son to Academy sports to get the last items for school, so I took the dually to make sure that I had no more vibration issues. Whew it looks like that did it! I still have to go get the front end aligned, but at least that is a normal part of any vehicle.
Now I can get on with some other projects, the bed, AC, finish the interior... You know simple things like that!
