Where do I find the name to put int the "classneutral," "classattack" etc. Also what does "classneutral," "classattack," etc. mean? Does "classattack" mean that what ever vehicle is in that slot, when the attacking team (team 1) controls it, they get that specific vehicle? "Neutral" meaning if the cp is gray, that vehicle will spawn?

Unless I'm mistaken, the Getting Started doc included in the modtools explains how to set up vehicle spawns.

As for where to find the name, you can look in each side's folder in your asset folder and open up the side.req file in notepad. That will list everything loaded from that side. (Which would include all the vehcles you can use)
