Question about titling a vehicle?

JAG notarizes for free. Now I too have ??? about this I bought my EP3 and paid taxes in GA for it already I am trying to register it in PA now. Will they make me pay taxes again? or should I show documentation about paying taxes in GA. I’m currently in Iraq so it sucks I can’t do much other than assist my wife with that stuff. Also since I’m stationed in GA I shouldn’t have to do a yearly inspection by PA’s standards since I’m military and stuck in GA.
