I went to the Toyota website and tried to use the "build your own" page. On this page, you have to choose a particular model configuration. The SR5 CM is not listed with a 5.7L, only the 4.7L engine. However, the Limited CM appears to be available with the 5.7L engine. Is this correct or is this just a website error? It would be strange and dissappointing if they only offered the 5.7L CM in the Limited model. Thanks,
