Selling 1 of my 2 former penitentiary transportation buses that is a beast and has the layout / design bones to quickly turn into an RV.
With a bathroom already there (and an adjacent section perfect for a shower), there are 2 rooms for building out a kitchenette and a bedroom.
At the entrance, you could use the cages as storage, etc ... or remove them.
Based on the fact that California maintained these buses, I know the mechanics are solid.
