I just bolted my receiver onto my frame up front. I use a locking pin to keep it secure to the receiver. I have thought about putting some spot welds on the bolts to make it more secure, but if someone were to unbolt it, they would have to figure out how to remove the locking part between the receiver and the hitch. I am sure it could be done with enough time and effort, but that is a whole lot of work to get my hitch from the storage lot. My feeling is they can steal a lot of other stuff in the lot much easier. The equal-i-zer brand hitch is really heavy. I got tired of moving it around.
