I've just looked at physical security, you know something that you bolt on to your hitch or wheel to act as a deterrent
So with that in mind lets look at hitch lock type security.
Sunncamp Trail Safe - Trailer/Caravan Hitchlock
The cheapest I came across was this one: SunnCamp Trail Safe - Trailer/Caravan Hitchlock bright yellow, a visible deterrent, with a metal shroud, a padlock and two keys. For the price its a cheap option, coming in at under £12.00
Personally I think these are perfect for your small car trailers, especially at that price!
Nimbus Heavy Duty Trailer Caravan Hitchlock
The next type actually clamps into your coupling with a bar looping over the top of the hitch handle, like this one: Heavy Duty Trailer Caravan Hitchlock
Again, a cheap solution with no padlock to fail so may be better. This one costs under £15.00
Milenco Super Heavy D Sold Secure AKS3004 Hitch Lock
The next one looks a little more like it should do, Sold Secure which is good and of a heavy looking construction being drill and cutter resistant. It can be fitted either hitched up or unhitched which is a good idea, especially when touring and stopping off at service stations. The Milenco Super Heavy D Sold Secure AKS3004 Hitch Lock is priced just under £55.00 a bit of a jump from the last two but in my opinion a better buy for your pride and joy. Milenco also do a version for a Winterhoff hitch as well.
1285810 - AL-KO 2004/3004 Safety Device
The best and most expensive one is the AL-KO as you would probably expect if you have an AL-KO coupling its probably best to fit a lock made by the same company. It can be fitted either when hitched up or unhitched. I really like the idea of having it hitched on, on our travels last year to South Wales I didn't much like the idea of leaving the caravan whilst we went and had a cuppa. This would of put my mind at rest. The AL-KO 2004/3004 Safety Device is certainly not the cheapest at just under £80.00 but we all know how good the AL-KO stabaliser is, so I reckon this should do the job perfectly.
There are many other different types available, but I've just picked out a few which
I would seriously consider.
I've given rough prices, as with everything these days, they can go up and they can go down, so please check. If you click on the links for each product you will get far more information and an up to date price.
I'll do a similar report on wheel clamps later.........
