A tip given to me by another RVer: When unhooking a motorhome-mounted towbar from the toad: (1) disconnect the electrical umbilical from the toad, (2) put the toad in Park and start the toad engine, (3)turn the toad steering wheel from lock to lock and then straighten up the wheels, (4) remove the pins and stow the towbar. Prior to learning of this tip, the towbar was frequently in just enough of a bind that it was very difficult to push the towbar extension release pins and/or remove the pins holding the towbar to the toad spreader bar. Holding the extension release pins and having someone else move the toad backward or forward will work but I have always been a little nervous about standing between 2 vehicles that are moving with respect to each other (plus the fact that I don't always have someone with me to move the car back and forth while I hold the extension pins down). Since learning this little trick, I have always been able to release the extension pins and/or pull the towbar pins without help and without getting a hernia.
