Your personal preferences, family, and career all play a part in which truck is the best option for you. Both will give you a front and back seat, but the extended cab truck will not give you a full set of back doors. If you rarely have passengers and just need a bit of extra interior space for transporting items, an extended cab will probably work and could cost you as much as $10,000 less than the larger crew cab. If you often share your vehicle with co-workers, kids, friends, etc. the crew cab is nice because it adds extra space for the driver and front and rear passengers. The four full-sized doors also make loading and unloading things easier.
