Towing an rPod with a modern fuel efficient vehicle is pretty much independent of what that vehicle is or what fuel economy it gets not towing. That is because the horsepower demand towing at highway speeds is dominated by air drag on the trailer. So, your mileage may vary, but mostly due to the speed you tow at, whether you're climbing hills or not. and if you have a headwind or tailwind. On flat ground with no wind you can expect to get around 15-16 mpg at 55 mph, about 14-15 mpg at 60, and down around 12 at 65 mph.
So, get a tow vehicle capable of handling the fully loaded trailer that can also carry a realistic amount of stuff in the TV itself, and have a safety margin above that. Forget the trailer empty weight specs. Do not get FWD, and get a tow vehicle that is approved for using a weight distribution hitch.
My Toyota Highlander fills that bill for the 179 or other similar sized rPods, but I wouldn't go any smaller than that. I tow at 60 and, sure enough, get 14 mpg under flat no wind conditions. I get a little better than the EPA book fuel economy with it not towing, around 19 city/24 highway.
