Hey man! Always good to see a local here.

I bet you really really long odds that it's tires, not suspension. My truck was doing the same thing you describe and it went away when I put on new tires a few weeks ago.

Shoot me a note if you would like a good source for tires, I know someone down your neck of the woods.
