Glad to connect with another ZR2 owner
nHoggard, I too just bought a ZR2, have had it 2 weeks now. I posted a review in the owner review section, I am copying it below. Lets keep in touch!
Bought my ZR2 2 weeks ago. Been pretty happy with it, except for one thing - the engine seems a little sluggish to me, especially at speeds over 40-50 mph. I was probably spoiled by my previous vehicle, a 2000 Dodge Dakota with the 4.7L V8. My solution has been to limit the gear to 5 in town and to 6 occasionally on the highway.
I did replace the rock rails with chevrolet's off road steps, sinc my family was complaining loudly about the step in height. I don't plan to do any serious rock crawling, so hopefully that will be ok.
there are also a few tech goodies that this truck lacks, like lane departure warning, collision avoidance, or active park assist, but those are not a big deal to me. One thing I would be interested in would be a surround view camera system, and I am looking into an aftermarket system for that.
Would love to hear other owner's thoughts!
