Thinking about buying my first :)

I towed a 3500 gvwr hybrid travel trailer with our 2007 honda odyssey (seems similar on paper to the Kia) before we switched to a bigger trailer/tow vehicle. Did some setup including transmission cooler, weigh dist hitch, brake controller and charge circuit and the honda did just fine. It was a bit under-powered but towed very well. I watched the weights and we were slightly over the van's gvwr but well within gcwr...honestly you'll see way more overloaded half and 3/4 tons out there.

I wouldn't have tried to tow through the mountains, but for where we live it worked great for us.
