While having concrete poured for parking RV at the house, I need to put it in storage. Placed is gated and all but what do y'all use for king pin locks? I don't want to spend a fortune on it...
I took a heavy chain that fits in the groove and cut it just long enough to wrap around the king pin and hook the chain ends together with a heavy duty padlock. Works great and very inexpensive. I've had the 5th wheel in 3 different storage lots and it hasn't walked away yet in 22 years.
