Most motorhome owners are now going back to steering wheel locks - my friends with a brand new McLouis have certainly done so, plus tracker. I have a tracker on my Triton which is excellent and very cheap, really. The tracker (a Rewire DB2) cost me £30 on Amazon and I pay an annual charge of £59.99 for the tracking service. I can see where my van is at any time and it gives me mileages travelled and, the really useful one, battery voltage, so i can go and swap out the battery in storage when it needs it. It also sends me text alerts if it moves from its current location. And it gets me an insurance discount.

Here's a screenshot of the app (I keep the page permanently open in my computer's browser and just click on refresh to get the latest data). I have removed identify names just to be safe.. There's also an app which i have on my phone...

Talking to someone recently who had a steering lock on their camper, the thief just cut a small section of the steering wheel out (much softer than the lock) and slipped the lock off. No idea what type the lock was.The camper was recovered sometime later. We had a snap off steering wheel on our last camper but modern steering wheels are far more complicated to do that with.

Basically I think if they are determined to have your property, whatever it is, the thieving scrotes will take it. You can put deterrents in their way but you can’t stop a determined thief.

It's not just a question of cost, but the hoops you're made to jump through with these gadgets. We have no requirements like wheel locks. We use a hitch lock but that's our choice.
