I have never had or driven a V10 equipped MH to compare, but our 2021 Thor Axis 24.1 with the V8 is definitely quiet. I hear more road noise coming through the wheel wells than engine noise. Thor/Ford did a good job of insulating the dog house.
I also average 12 mpg over 5,000 miles. I get a little more, maybe 12.5 on flat interstates and a bit less, 11.5 on twisty country roads. These are fill to fill calculations.
I just filled it up and hit a 13.5 mpg average over 10 miles of flat interstate before I got off into hilly secondary roads and it dropped. This was a dash reading.
