I have a neighbour with a Ferrari ( at $360,000 ) and he lets his big dog in and out of it. The dogs in at the shopping centre, barking and running after every person walking near etc.
Good security.
If you have it - use it.
Agree with you that I would have the SVT out each day washing and polishing rather than loading the stone and bricks into it.
Then again they are just trucks.
Cheers
