Here's my data point: Valencia 38RW, 4300 miles driven, 8.95 mpg average.
The way I see it, the main variables are:
- How aggressive/fast you drive. Wind resistance (drag) increases with the square of the speed driven. The difference even between 65 and 70 mph is discernable at the pump. I'm about average I guess, I tend to drive 65, max 70 on the 75-80 mph highways around here.
- Toad or trailer. A 2500 pickup is going to lower your mpg more than a Fiat, and a big heavy trailer even moreso. We have a midsize suv as our toad.
- Driving conditions (wind/mountains). Most of our miles driven have been in Colorado (mountains) and Wyoming (wind).
- Generator use. We frequently boondock and so use our generator a fair amount. We've added 68 hours on the gen since buying the rig in May.
If all of the above are the same between two data points I don't think the gas mileage difference between a Verona and a Valencia is going to be more than 5-10%. They have the same cross sectional area which is the biggest factor and weight is fairly close.
I also expect to see people claim that they get 11-12 mpg towing a 15k lbs stacker trailer with their Verona through the rockies, as that's the nature of the Internet.
