This is what I have and it's great. It was around $10 - $12 dollars from the dealer. Part #12496641. It is made out of rubber and slips over the receiver tube. It just flips up when drawbar is in place and then you flip it down and snap it back on when drawbar is removed. Don't know if it is what you had in mind, but it doesn't need to be removed and stowed when towing.
