Will the Immobilizer II # BX88225 Work with a 2 Trailer Hitch Receiver Collar

Question:

I have a Motorhome with a 10,000 LB Receiver. I need a Hitch Immobilizer for Flat towing my F150. The receiver takes a 2 inch square Pipe. The problem is that the collar around the receiver on the Motorhome is 3 1/4 inch as measured from side to side or top to bottom. Will this 2.5 inch work on this receiver?

Even if the Immobilizer II # BX88225 did fit around your receiver, since it is for a 2-1/2" receiver opening anything that you put in the trailer hitch receiver would be too small for this to work properly.

Instead I believe what you would need is the Immobilizer III # BX88312 which has a bracket that is 4" x 4" and is compatible with a 2" receiver opening. I have attached a photo showing these dimensions. I recommend trying to mock up this on your trailer hitch to see if this is compatible with your application or not.
