Crew cab trucks are designed to haul people along with cargo and are prized by families and contractors alike for their ability to stand in as daily drivers and troop transporters whether your final destination is soccer practice or the job site. Not all crew cab trucks are created equal when it comes to how much room they have to offer their up-to-6 passengers, which is why we put together this list of the biggest crew cab trucks. We had to choose one particular measurement to use as our yardstick, so we went with rear leg room, figuring not getting crushed behind the driver is the most important characteristic of any 2-row vehicle. Let's take a quick look at 8 of the biggest crew cab pickups available, based on rear leg room.
