The only thing that I would want is to add brakes to the trailer as most small trailers don't come with brakes.
I would go with a Nissan Frontier with the 4.0 V6 it is the best midsize truck on the market, and the 4.0 pulls like a V8 without the gas guzzling. I'm certain you would get more than 9 mpg I'm betting a good bit more.
