Well I bought a Crookstopper removable post & I must say it appears to be a substantial piece of equipment.
I’m going to put it in so the lock needs to be accessed from behind the post, if anyone wants to get the bolt croppers going they’ll have to lie under the caravan, except they’ll need to grind the steel protective plate off first.
An angle grinder would take a while due to the gauge of the steel & a Stihl saw with a metal cutting blade would attract attention. You can only do what you can or what’s feasible.
I know, I know, if they want it they’ll have it.
