My dad had a custom-made LR and two people could very comfortably live out of it for any length of time. It even had a water tank with a heated shower head if you were feeling lavish.
The tent was on the roof so it should have been safe from most animals:
I wish, but no - it was a replica made by a specialist LR garage in Poland. My dad bought it for an expedition to Kazakhstan in 2014, but unfortunately, cancer had other plans. I've inherited the LR but sold it shortly after because I had no use for it.
