Well Ogre. Some of us want to explore and not go with large family caravans to holiday parks. Some old farts like me want hygiene and privacy - so I want a reasonable shower - not a large wet room. I only want a2 + occasional 2, but for drinks cabinet - I want a largish (152 litre (5cuft) fridge freezer -also for some food. But hob will do. No oven cooking on hols.
Most important thing is my own permanent bed (my design)for a good nights sleep.
And guess what - all in a 2 x6m sized 5th wheel - modified by a North American manufacturer!
