I hate it you called me out, lol, this is going to be pretty ugly... (but hey, what are the internet friends for, after all, right?!). If there is one thing I dislike about the LC200 it's the miserable range when towing, to the point I'm considering installing an auxiliary 10gal tank to extend the range, as many do if taking off road.
Yeah, I have the numbers for you, the numbers are bad enough I feel I need to make a disclaimer, lol (to accommodate my complicated work schedule plus last minute delays I needed to push it a little bit).
Twoing to AZ/UT mostly uphill (slightly above speed limit of 75mph) my worst fuel economy was in the stretch around Flagstaff (7,000ft) where it hovered between 7-8mpg. With a 20+ (24?) gal fuel tank that gave me the range of about... 150 miles (sic). Bad enough? lol.
With that said it was single digits all the way. When towing the 240 I start looking for fuel at about 100 miles past the latest gas stop, and then go into advanced search mode at about 150 miles on the clock, the max range being basically below 200 in that scenario. I can see 10-11, sometimes even 12 mpg, for example on trips back from Arkansas at a leisurely pace towing the 240, but that's only when going slower and generally over a slightly descending route.
(for reference - when not towing I get 14-16mpg depending on time of year and routes. )
Now, the Q7 TDI - that was a different story! 12-14mpg was about the lowest I've ever seen (~30 daily non towing) but we all know diesel (especially TDI) rules in towing.
