Friend claims 18 mpg while towing 35' toy hauler with 2003 Dodge Cummins Diesel with manual transmission. He says he never goes over 55 mph. Is he for real?

I have an acquaintance with an 01 ram 5.9 auto that claims he gets 18 as well towing a tt. I just smile and say oh wow thats really good.
I also met a guy when driving my work truck . Work truck is 14 chevy 3500 dmax. Guy walks up asks how I like it. I tell hi, I dont like it, I love it. He says what about milage towing? I say 12 to 13. He says oh wow! Turns and points at his ram and says I get 18 mpg all the time even towing. Again, I respond with, oh thats really good!
Lol if somebody really thinks they get that type of milage towing these large trailers I just smile. I know I wont be able to convince them they are wrong.
Actually, I met a guy this year camping that gets 12 towing his no slide 29' bumper pull. He drives an early 2000's gas 5.7 hemi...... hmmmm
but he was a good we chatted lots through the long weekend.
