I have a v6 rcsb, got ir back in Febreuary and right now it has 20k miles on the clock.
No 1/4 times here but mileage is a consistent 19/23 city/highway with a really heavy foot. It may not sound like much but I'm in México and we get worse mileage than in the US because of the smaller streets and heavy traffic.
The truck is fast for a v6, in fact it's almost as fast as a stock nbs 5.3. Just to give you an idea on how bad is mileage down here, back when my '06 was stock I was getting 13/16 mpg in city/highway conditions.
So far I'm impressed by this little v6.

I'd love to install a turbo but not going to happen as it's a company truck.
I'll install 3.90 gears and a BB tune as soon as it runs out of warranty. Shouldn't take more than a month as I've put around 5k miles/month so far lol

I have a new sierra rcsb with the 4.3, and I average 21mpg around town with some backroads driving.
Plenty of power when needed and I don't tow anything either.

Don't get me wrong they can't match a v8 but it's the first time I've been impressed by a v6 on a truck.
