Caravans as BOLs / retreats

[NorthernRaider]

Just thinking aloud and decided I would like to get other peoples opinions on the concept of buying and refurbishing a two berth caravan and finding some place to site it that is not a caravan site.

Few of us can afford 2nd homes, or even afford to move out of town, but you can still buy used if tired but stil servicable caravans from about £300. Providing they are structurally sound and waterproof they can be gradually refitted and upgraded into usual temporary liesure or survival accomodation.
I used to have a tiny 9 ft 6 in long Compass Shadow two berth caravan, it had an end kitchen, toilet shower, storage space and could easily sleep three ( more in an orning if neccessary)

If we could find farmers, land owners etc to rent a piece of land from or buy small remote spots of forest we can legally set up a " shelter" to protect us from the elements as we tend the woodland we could end up with neat usuable weekend retreats.

Thoughts anyone?
