awesome, i didnt see any responses to that thread...
my next question would be this...you mention the 5100's, WHAT IS YOUR END GOAL...this can really determine whether or not you will be happy with your selection.
the 5100 is great option, but many do comment that it feels stiff and somewhat (harsh) for daily ride quality. I really think far to many people expect a truck to ride like a Buick 225. Can it, YES...i can adjust mine to be so soft it feels very floaty. IT is soft and ride is PLUSH, but you feel more tired from all the movement.
there are a few great options to look at, if possible try to find trucks with something you like and ride in it first.
