Hitch coupler lock

Mellow_Yellow

I was considering the Proven Locks, but I opted for 3 separate locks because I can use one of them while towing. 
1) Update: this locking pin is long enough for the T@B 320 hitch coupler but is a piece of crap. It seized up after only 1 month in west coast rain:

It can be used both while towing/parked to deter theft.
2) When parked, I also utilize:
a wheel lock: https://www.amazon.com/Trimax-TCL65-Wheel-Chock-Lock/dp/B0031XULF2/ref=sr_1_11?crid=1YB9BNDMHKKAN&dchild=1&keywords=trimax+tcl65+wheel+chock+lock&qid=1606501195&sprefix=trimax+TCL,aps,217&sr=8-11
3) and a lower end coupler lock like this: https://www.canadiantire.ca/en/pdp/reese-towpower-professional-coupler-lock-0406968p.html#srp
