The best place to find rockhoppers is in Dawnshroud Peaks. There is a cave full of them just to the right of the patch of angry mushrooms. It is the only cave system that shows up on the map.
The only thing to remeber when killing these rockhoppers is NOT to kill the " Age Old Rockhopper". Once he has been killed the rockhoppers will stop popping and the cavemen will take over..NOt good.
there is a merchant in the small village close to the cave that you can sell the stuff you pick up and do not want to keep. You can keep your packs clean and make a few extra gold.
