Nice thought taking the hitch off, but there are a couple of things to bear in mind.
First of all most insurance companies insist on a hitch lock being in place and being used. So by removing the hitch I could well see the insurance company using that technicality to avoid their obligation to cough up.
Second. As the retaining bolts are what is known as single use only, being of a shake proof, self locking nature, there is a significant cost in keeping a stock of new nuts and bolts. Also here, just remember the insurance policy again.
Finally. Do you realy think that the proffessional criminal is not going to have a spare. After all, 80% of caravans have Aalco hitches and as far as Im aware, they all share the same hole layout and pitch between mounting holes. One could arguably say that by taking the hitch off and not being able to put a locking device in place, then one has just made the thief's job easier.
You have to remember that a thief goes equipped to do his/her job efficiently with minimal fuss. I saw a typical example of this the other day. I was in a carpark when a Transit pick up with high sides drove in, nicely painted with a yellow cab simlar to most local authority roadworks vehicles. There was a black tipper body on the back and as mentioned before a sheet of plywood attatched to make a high sides body. Then i noticed a rather odd attatchment, a skip loader was also fitted to the back of the tipper body and the high sides were cut to blend in with the profile of the skip loader arm. Also it had the customary tow bar fitted too.
Not that unusual I hear folks say, but just think like a thief. The truck to all intensive purposes looks like a local roadworks contract vehicle. It has capability to lift loads quickly and quietly onto it. It also has the facility to dump the contents quickly should it need to!
To me, a security conscious person, it was the perfect tool to lift generators for instance up and into that high sided hideaway of a body and if I was rumbled just back into a field a tip the loot, to go back to Mr innocent.
