You're right, it really isn't that much of a difference.
There are some trailers that could allow you to get 14 or 15 mpg. A hardside popup like my Aliner (I get 16-17 mpg) or a Trailmanor or HiLo, a molded fiberglass 'egg' trailer like Scamp or Casita, or possibly an Airstream would fit the bill. However, even raising fuel economy from 10 to 15 mpg would be less than a grand per year.
I am pulling a 2015 3124KD Trailmanor with a 2005 Avalanche 1500 on the east coast. My normal MPG is around 20 and towing I get 16+. Unexpectedly, I get my best MPG in the "mountain" areas. However to do that I have to be willing to open and close the Trailmanor, open and close the inside bathroom, have a smaller bathroom, a half size refrigerator, etc. It is all about compromises. My Trailmanor tows quite nicely and I do not mind the setup, but others do...
