One of two things is causing your vibration going down the road.
First check the easy items and see if any of your tires are bulging, showing cords, or just plain wore out.
I would bet since you mentioned drivetrain and considering the age of your truck that the U joints are wore out on the rear driveshaft. Check and see how loose they are, if the rubber seals are wore out, etc. If they are the non-greasable type and your truck has a lot of miles, its time to replace them. Or on the other hand, if they are greasable and you don't regularly grease them at the oil change, then they are definitely shot.
You didn't state if your truck is an extended cab. If it is the carrier bearing that helps support the longer driveshaft may be wore out as well. That is very easy to see on a mechanics creeper under the truck.
If you do this yourself, make sure you have a good vice, hammer, and potentially a cutting torch. Removing the driveshaft from the truck is the easy part, the rest is not as much fun.
Good luck
Depends on the drivetrain.
I have a 2005 civic lx and I get about 40 or more sometimes on the highway. And something like 36 in the city.
Yes, although a freeway can sometimes be faster than a highway.

They are a country band.
A highway interchange is where two major roads intersect or come together. Sometimes, both highways run together for a distance after an interchange.
Front or Rear wheel bearings may need changing, can be a tire out of balance, bent wheel, motor count broken, just to name a few things.
Wet, consistent noises.
You can attempt to sue anyone for anything. Whether your lawsuit would have any chance at success would depend largely on: a) is the city responsible for the highway? usually a highway is the responsibility of the state or federal government, in which case the city is not liable regardless b) did the 'something left in the highway' cause you actual damage? you cannot sue just because someone theoretically did something wrong -- you can only sue if you have incurred damages of some kind c) should the city/state/whoever reasonably have known that 'something' was left in the highway? if they routinely check they may be less liable than if they never check.
The idiom "highway robbery" originated from actual incidents of bandits robbing travelers on the highway during medieval times. It is now used to describe a situation where prices or fees are unreasonably high or unfair, similar to being robbed.
Um... a street? Well, there isn't really an antonym because its not something that is considered word. Its something that was made up for the long streets.
