This trophy is gained by Trevor ONLY! 5 rampages, all rather easy. Just be careful with the 4th as they come with 2 or 3 tanks..... plus troop trucks..... Also I'd like to mention that if you are going for the Gold Medals for the "Solid Gold Baby" trophy, the requirements on the rampages do not stack like the missions and strangers and freaks. Here is a video regarding the trophy and how to do it. I have not made it, this video was made by PhatSteve7 so all video credits go to him :) hope this helps and good luck :)
