Also good for crawling through parking garages. 3rd gets you up to speed quick and is perfect for turns. I've got a fairly torquey motor also, and 4th is good for a pretty large range, from sharp curves at ~1500rpm to up to 55-60mph which my tach says is 2500-3000 rpm. I would not be comfortable getting out on the highway where anything less than 70mph is obstructing traffic around here. I've got fairly loud mufflers and an imperfectly balanced drivetrain and driving a sustained 3000+ rpm isn't comfortable due to noise and light vibration. My truck seems to feel most comfortable cruising at around 2000-2500 rpm. I will be attempting to do my NV4500 swap this weekend and I'm looking forward to seeing how that works out. Hope this helps.
