> what plastic components have you removed?
I did that quite some time ago so I don't remember. Looking at Granite Gear's photos on their Web site it appears the stuff I removed may not be included with the current models anyway.
> What kind of shape is it in?
It is in pristine shape. A bit of dirt and that's all. I don't think I've had it in the field more than three times.
> What is the height dimension?
I'll have to measure it when I'm at home, but it's tall enough to sit up in.

I've not had a current model in my hand but judging by the photos on the GG site the one I have appears to be stock.
