I think the 16.8 mpg towing a Suzuki Jimny is much more realistic. A small, light towed vehicle should hardly affect fuel mileage. When I had an E450 based class C, of course it got much worse mileage, but towing a 3200 pound vehicle cost me less than 1 mpg. As far as getting almost 26 mpg in an 11000 lb motorhome? I think they adopted in Australia the time-tested American method of increase fuel economy- make up numbers to impress the internet!
I hesitate using the word "impossible" with respect to the 26 mpg claim ... but maybe that word fits here?
