This thread brings back some memories. On some of the leases we had in Scotland, we'd buy a cheap at the end of its life caravan
(trailer) and set it up as a semi-permanent "camp".

We'd usually spend some time curing leaks, doing repairs and modifications before taking it up, but once in the woods, it was generally left in position.

These were caravans we might pay $150 for "scrap value" so to speak. It was not worth paying more as there was always a risk some scrote would break in and trash it.

Over the years we got lucky and apart from the odd break in, we suffered no serious damage apart from a forced lock. When we left one lease, we sold the caravan to some bird shooters who were also on the ground, and we heard that within a month they had found it trashed so I guess we have been lucky..
