I like the 2 door ones better. Have you done a photoshop picture to see what it will look like? If you don't have a digital camera take a photo of the side view and get several copies made then cut and paste a mockup. Would you strech the frame or shorten the bed? It makes me think of the AMC Pacer strech limo in Wayne's World. Longer doesn't mean better. I've seen a lot of old pickups streched out into a crew cab and they're interesting but not as attractive as the original truck. Do you need two more doors? How big is your crew? Don't any of them have their own transportation?
