Sure,

Wheel travel is the total distance that the wheel travels when all components are installed ie. Shocks, axles, limiting straps or anything else that restricts the up and down motion of the wheel. Generally, the more wheel travel that you have the better. Travel will be most noticable on whoop roads and the rough stuff. The goal is for the suspension to "suck up" all of the bumps and for the chassis to remain smooth. Travel and suspension is the main factor on how fast an off road car can go (given that you have the motor). I hope that explains it. And thanks for the comments on my car.
