What is the difference between an rc truck, truggy, and buggy?

I know what they look like, so I want 2 know what their advantages are. I want a really durable offroad rc that's good for jumps and that drives well in rough terrains, like sand, and rough dirt. Which type of rc car would be good for that?

Well for an r vehicle that runs the way you want it, I would suggest a Traxxas Rustler or Traxxas Stampede. They are 100% waterproof, Fast, Incredibly durable, and come with everything you need to get started in RC. Traxxas cars are really good for beginners, and i know they are expensive, but well worth it. They have really good tech support too. Whatever you do, don't buy an Exceed RC car, they are cheep and terrible!
