Hands down it is Four down! We've towed our Liberty for 9 years and it has about half as many miles towed as it has driven! We figure roughly 45k towed and about 90k on the Odo. Hook up is very simple, we have a built in brake system, not a suitcase. I wanted to have as little to do as is possible when getting ready to go. I have nothing to store except a small canvas bag with the cables and pins in it. Do read the Guide and then verify with the MFG. Do get a Toad that you like to drive. Then go out and enjoy.
