Always use safety chains when
towing.
Cross safety chains under coupling to
prevent tongue from dropping to

Allow only enough slack for tight

Make sure hitch and ball are properly
sized, match each other, and are
fully engaged.
On optional ball couplers, always
insert hitch safety pin before towing.
