Yes, yes, yes. Of course. If it won't kill you to fill up more often, get the 4.7. The 3.7 will get you around, but it won't impress you.

not that i ever tested a 4.7, but from what i've been reading around its your best bet over a 3.7 . I've been driving my 3.7 WK since 2005, i had no issues with it accept that its under power, body is too heavy for that engine, and about gas saving, it wont be that much differnce between both, maybe a mile or 2 less per gallon....... so if i had a chance and go back in time, i would for sure get the 4.7L .

Good luck.
