Towing a Honda fit

for what its worth, and I know the whole" my brother in laws, friends cousin told me" but I did talk with a guy who had a camper and truck very close to mine and he says he pulls a jeep flat, no brakes, never a problem. Again for what its worth. Id hook the whole thing up and take a couple of test drives, hit the brakes, make a couple of quick lane changes and see how things react. You will know pretty quick it its going to work for you for one trip or if its too out of control for you. Then make up your mind what the right thing to do.
If things are too crazy after your test drive you can always add the brake equipment, then you will always have the towing equipment to use later.
