Tried the hookup & pull the MH forward approach. Found that sometimes both arms would not lock. Go around first corner and see the Jeep tracking weird.
Have found best way is to collapse the arms, and have wife approach. Try to center toad as much as possible. Connect towbar to toad. If arms are extended roughly same distance, back up slowly until they lock in place, then complete cable hookups.
If arms aren't extended equally, turn the wheels of the toad toward the long arm so when you back up, you pull out the short arm slightly more. After a few times, you get a good feel for how much you need to crank the wheels to compensate. Remember to straighten wheels out after bars locked.
You can do a quick check that both sides are locked by feeling the bottom of the handle assembly. When locked, nut is flush with bottom. When not locked, nut is recessed up inside assembly.
