True definition of a motorised caravan?

Probably best to avoid Bolton Abbey site.😂

It has longevity, been parking there abouts day in day out for the last ten years to my knowledge. Clearly of excellent watertight construction. Particularly like that cassette clearly positioned around head height. 🤪

I saw that same vehicle in Scarborough. Last week but did not take a picture, it was parked in Quay lane

There’s a caravan converted to fit onto a truck bed not far from where we live, looks very well done as well.
That simply doesn’t look roadworthy to be honest. If only we had policemen that checked MOT status, now there’s an idea......
