Off-roadingMany people want trucks to go off-roading, hitting the trails on terrain many vehicles couldn't withstand. While gas-powered trucks can certainly do a fine job, diesel is the way to go for most people who make off-roading a part of life. This all comes down to the aforementioned superior torque, as people generally don't need to worry about accelerating or high speeds when off-roading (not that anyone should be going too fast on rocky terrain anyway). This allows diesel trucks to utilize energy more efficiently and even haul larger items in case someone needs to bring something heavy out into the wilderness with them. But that's not all. Since diesel trucks offer greater fuel economy, there's not as much of a concern about running out of fuel in the middle of the woods or desert. Going back to the diesel engine exhaust brake, these types of trucks are more reliable when it comes to slowing down without wearing down brake pads, which may come in handy when going down inclines. However, there's a slight caveat with all this. Diesel trucks probably aren't ideal when driving over significant mud, especially if entering at more of a downward angle. Diesel engines at the front of the truck tend to weigh more than gas ones, running the risk of getting stuck in the mud if not traversing the terrain carefully. When it comes to rocks and hills, diesel engines have the power off-roaders require.Winner: Diesel Pickup Trucks
