Newcomers to night lighting often think that a mere absence of light represents night. This is not so. Standard three point lighting applies for night shooting as well. Essentially you light just as in a studio, but the viewer accepts that this is night because the scene moves to black where our light doesn't fall. Let the sun be a backlight, bounce in a little fill if needed, fool the color balance, by balancing through an orange gel or other method, so everything looks bluish, increase the contrast in post.
Outdoor lighting is much too expensive for a lot of people.
A generator big enough to run a 10K plus some other stuff is going to be expensive and probably too loud, even if blimped, to shoot on a deserted road. You would most likely need to replace the audio like the big guys do. That 10K would most likely want to be rigged very high, perhaps hanging off a crane, very expensive. As always, the sun provides a very nice, inexpensive light source. Any exterior shot can be expensive to light or inexpensive, depending upon how resourceful you are.
