Picked up my new khaki Rubi w/black hard top today and noticed that it revs and feels very different from the TJ Sport that I test drove a few months back (I never test drove a Rubi, just knew I wanted one). I suspect that it's due to the axle gearing. My question is this: when driving it around the city what rev range do you keep it in and what gear? It feels as though I'm revving it too much when I approach 3000-4000 rpms. I've never owned an inline 6 so the way this rig hums confuses me.
