The biggest problem with the L5P is they are heavy. A typical 4x4 crew cab short bed truck is around 8400 lbs stock. Once you add big wheels/tires, lifts, stereo, etc that most people do, it's not hard to get past 9k lbs. It's not like back in the day when people were actually trying to make their truck run at the track. They just want to look cool and sound cool.
