I have had a chance to run it, the chassis and truck work very,very well. The suspension is butter smooth,the ground clearance it great, and the truck side hills very well. I love the Rovers, I have 1 and 1/2 NWTT foams in each tire. As for the lexan running from the skid to the rear axle, it frikin works great. I was at a comp in Oklahoma and it saved my butt from getting hung up.
