Re: trade 4.7 for 5.7
It all depends are you a person who wants the hemi? You may get less MPG's, and more parts wear since you will likely be using more power. The quadra dr is good, but are you going rock crawling? The navigation radio is decent when compared to something for the same price that you could put in yours. Do you have children that would use the rear DVD? Has your truck been problematic, or relatively problem free? Does the other truck have documentation showing a good history so you can make sure it's a decent truck? You have stated that your warranty is still in effect what about the other truck? Do you have better things to do with $3000.00?
I think if you weigh the pro's, and con's you will make the best decision for you, and your family.
