Security while at home

Hi all

My wife and I have just taken possession of our AutoSleeper Nuevo EK.  We have been away in the"Beast" as our neighbour calls it and had a great time in Llangollen, walking over the aqueduct etc..  BUT now we are back at home and our A/S Nuevo is on the drive, I was wondering what is the best way of keeping it secure.  I tried the wheel clamp that I used when I had a caravan but it won't accommodate the thicker motorhome tyres.  Does anyone have any suggestions?  Wheel clamp and / or steering wheel lock?  Would be interested in any thoughts / advice / stories of experiences.

You'll get lots of different opinions but I'll kick it off -
Thatcham approved steering wheel lock 
Thatcham Cat 1 alarm
Milenco habitation door lock
Clutch claw on the pedals.

I just have my alarm set and a notice in the cab windows , as it is my everyday vehicle cannot do with wheel clamps steering wheel locks etc, if someone wants it they will take it regardless.

A visual deterrent is always a good way to go.
This was debated on here a while ago:
