I wouldn't want to trade a V6 RAV for a 4th generation 4 cyl. RAV unless the V6 was worn out or giving a lot of trouble. One can still have a V6 Hyundai Santa Fe or a Kia Sorento with advanced safety features as examples of alternatives. But to each their own, as the saying has it . . .
+1 on the Hybrid, I drove a V6 Rav4 for the better part of 9yrs, the power was nice, pulled my 2000lb boat just fine, but that power is not needed all the time, the Hybrid has plenty of power when needed, I sold the boat, so no longer need to tow that much, the Hybrid is still rated to tow 1750lbs and getting an overall 35mpg city/highway average is certainly a big plus, and it's hard to beat Toyota Hybrids for longevity.
