Wondering if there is a towing package available for my 2010 Kia Rio LX that I have. I currently own 2 large dogs (that take up the backseat) and a lot of hunting gear. I didn't know if a 4x6 cargo trailer is perfect my small little vehicle. I will be checking to see if I can put a towing package on it and how much the weight my vehicle is. Since its a 4 cyl, I am a little unsure. If I can't, is there anything that I can get to give my vehicle some more room?
