actually considered such myself
even with my small motor, the Sonata is supposely rated for 1000 lbs tow, trailer included. That would be enough with a 4x8 light trailer to handle a lot of hauling needs, like taking a mower, tiller, etc somewere for work and even small lumber loads.
don't need a minivan, about the only time now anyone is riding with me is my parents, or giving someone a ride to work or to drop off / pick up their car.
The Sonata is quite comfortable for 4, and gets 30 mpg.
