[Mr. Adventure]

The Purdue piece casts light on many possible problems at the hitch point, and I'm always a fan of considering possible problems carefully in hopes of avoiding unintentional adventures. I always put a lock on the tongue when the TM is in storage and I can't think of any good reason not to do that when towing.

But I've never had a hitch latch pop open unexpectedly in all those years with all those trailers. And, having calculated it carefully with our WDH discussions, the WDH plus the tongue weight together provide 1150# holding the tongue to the hitch ball, so the odds of the TM bouncing off the hitch ball are already pretty remote, IMO.

Far greater are the odds of forgetting to latch the top half of the door, put the chocks aboard, check the tires, attach the safety cables, or any of those other things we do when hitching up. Because it is so easy to forget things that are no problem at the time, I always do a final walk around before getting into the driver's seat, and another walk around every time we stop enroute.
