Back seats aren't huge in most extended cab pickups, which means you may want to consider a crew cab if you have passengers frequently. If you're only getting a larger cab for some enclosed storage space, an extended cab will likely work just fine. You'll also want to consider a truck's cost. Extended cab pickups are often several thousand dollars less expensive than crew cab models. But it's not all about the upfront cost, as crew cabs will likely have better resale value. The result is that a little more money spent initially may result in a little more cash in your pocket when the time comes to sell.
