I've never owned a 4.7, but have driven a friend's 2007 Ram 1500 4X4 that has one, and am impressed with the performance compared to my same truck of the 2001 model year with a 5.2. HOWEVER, when, not if, but when it's time to replace that 4.7 (they all fail eventually) you'll spend twice the money of a 5.2/5.9 ... IF you're lucky enough to find one.
