I looked at a spec sheet for an 07 CrewMax this morning, and the curb weight is listed at around 5,300 pounds. That's nearly twice the weight of the Tacoma I've been driving. I'm sure this is why they don't offer a V6 in the CrewMax - just too much iron and steel to pull around with a small engine.

As for the two V8s, I'm still a little perplexed as to why we are offered this choice if the bigger one gets better gas mileage. The best answer I've been given as to how a larger displacement V8 can get better mileage than a smaller one is the 6-speed transmission that allows more efficient power than the 5-speed tranny that goes with the 4.7.

So for most folks, it's a no-brainer unless cost is an issue. The 5.7 costs about $1,200 more. Otherwise, I don't see any real advantage to getting the smaller V8.
