Basically, a buggy takes a buggy body specifically for that chassis. Truck bodies you can fake a little with a different body (associated on a losi or vice versa), but it involves cutting creatively to get the shocktowers to fit, which defeats the purpose of running the body at all (it's the first line of defense, after all).
However, there are about a half dozen body manufacturers, and if you run a common chassis, you can probably find different styles. Proline is probably the best known, but parma has some, as do Jconcepts (probably second most popular after proline). Each company usually has a couple bodies as they tend to update styles (the xxx nt has at least 3 that losi has made). Also look for Dahms (has a new owner now) or Bolink (if you can find them). Atomic also makes some bodies for the Associated cars.
