I have seen some 4 cylinder stick shift Hondas and Toyotas getting from 18 to 22 mpg with a 13'er. People with small diesels (Jetta, Passat, maybe Chevy Cruze) seem to get high 20s, but they are towing over their rated capacity (usually 1000 lb). The 3L diesel in the Grand Cherokee should
get low 20s, but I have no data. Other than those types of vehicles, I think you will find that 15-17 mpg is very, very common among those who tow a 13'.
The best thing to do is relax and forget about the mpg's. Go camping, enjoy yourself, enjoy the trailer. Next time you need a replacement vehicle, you can decide if you want to shoot for one of the above types (or something new might have come out by then) for greater fuel economy. But trading vehicles when you don't need to, just to get a couple extra mpg's, will almost always cost more than the fuel saved.
