>>So neat, only outside stuff is one small fold up bucket.
First of all, welcome! We agree with your point, and don't even have a waste bucket outside. That's because we use serviced sites 99% of the time, and don't normally bother to use the sink. It makes for an easy life, especially if you don't plan to stay in one place for long. But not everyone sees it that way - quite a few owners convert the water supply to allow use of an aquaroll.
Awnings are another thing that we just don't get, but that too puts us in a tiny minority! I suppose the point is that there are as many ways to use an Eriba as there are owners. Well, almost.
On the Smallhausen thing, Eriba owners are seen as a bit odd in the UK, where it seems that bigger is better and living a simple life is not what most caravanners are looking for.
