We are taking our trailer (for the first time) away with us, I just wondered is there anything we can buy so the trailer is locked to the towbar, so when we are parked in a car park etc no one can just unhitch the trailer and go off with it?
loads on e bay just type in bulldog mini hitch lock.
if you buy one make sure it has the flat plate with the welded on loop.
It can be used when the trailer is hitched or unhitched
Most hitch locks can be used to lock trailer to car. Do you already have a hitch lock that you use when trailer is parked? If so try it with trailer hitched to car, it will probably fit.
