No pics yet sorry, but hey you know what they look like.
As for fuel, I checked a couple of reviews before I bought it and I didn't see any reports of bad mileage.
This is replacing my 1996 4.0 straight 6 Cherokee and so far it seems at least as good on fuel, in fact it might even be better but I'm struggling to believe that. I had a '95 4.0 before the '96 and it was about the same too, so it's not just that my '96 was a bad one.
I know a bloke with a 4.7 Ram and he also says his is good on fuel.
I'm still getting used to the level of equipment it has, I keep finding new things. I think I wouldn't be surprised to find a multi-ball feature.
