Two new Mack Trucks are being added as downloadable content to the popular Snow Runner off-road trucking simulation game.

Off-Road vehicles are built to hit the trails and backroads, and the MotorTrend Off-Road section has the latest on 4x4 Jeeps, trucks, and other off-road rugged machines.

Looking to take your rugged vehicle off road, but not sure where to find the best trails? There's an app for that. Actually, three of the best of them.
