We just finished a 1,000 mile trip in a Cruise America 30 with the V10. Despite the noise I was impressed with the engine (86,000 miles). We averaged just under 9mpg and I think the tank wasn't quite full when we got it. Las Vegas, Zion, Bryce, Sedona, to Phoenix so some mountain travel. I did not use tow/haul mode except in some severe situations. Only used 87 octane except one tank in Utah (I think) which was 85. Did not notice any pinging.
