I agree. The dyno chart comparison between the 5.7 and 6.4 would be interesting to see. I was surprised there isn't more difference than there is between the two.
$1500 does seem steep for the small difference, but then again, it is a lot better than the almost $8,000 for the Cummins

(see My Pics) I have put 5000 miles on it in two months. half of which is back and forth to Our place up North in Mi. if I keep it under 70mph I float right around 14-16mpg. once I get up into the 80s the mpgs drop to 11-12. I have towed My 3 place open sled trailer up and back once so far and got around 10mpg. the trailer and whats on it weighed about 3000 pounds.
Hope this helps
That's the kind of info I'm looking for. Thanks. Our travel trailer weighs about about 6,000 fully loaded. My Cummins towed it like it wasn't even back there, but in all honesty, I didn't even check the mileage.
I would really miss the exhaust brake, if I end up going with a Hemi.
Before we towed the trailer up to our hunting camp, I had a problem with the trailer brakes, so I disconnected them. I went down a 6% grade that is about 2 miles long and has quite a few curves in it, and I maintained 50-52 mph and never touched the brakes
