And......
My 86 VW delivers 14-16 mpg's on a consistent basis.
My engine is bigger than yours but pushing more weight.
Going across South Dakota headed West with a 30-40 mph headwind I got 12 mpg and could barely do 65 mph.
By contrast, I just purchased an 03 Dodge Ram Van, New Tires, 106,000 miles, runs strong, 5.2 engine (318), automatic, dual air, tilt wheel, factory cruise, ABS, air bags, heat enough to roast a Pig, and is EPA rated at 13/16 mpg.
It is bigger, more powerful and when I am done with it, it will be multiple times more comfortable for sleeping and will have a full bathroom in it!
I paid $2,500 for it.
I anticipate investing $2-3,000 more to turn it into a class B Camper.
In my VW loving opinion, my Dodge is a far better value.
But as mentioned above.......
ZERO "cool" factor driving an old Dodge Ram Van!
