Family caravan layouts.

[Chicken Chaser]

I'm looking to canvas the opinion of those with families and vans who can pass comment on what layouts work best.
It'll be for 2 adults a 4 year old and another which is yet to be sprung.
I can't see a fixed bed being a good option (a shame as there are so many) and a centre bathroom seems to restrict space however, it does mean that they're out of the way at night.
Side dinettes seem to be plentiful but not sure if they would be too close to us at night when we want to kick back in the evening?

I'm on a B licence at present with a max limit of 1400kg (car is 2100kg all up) which means I might need to upgrade my licence for the sake of 50kg.

We are seasoned campers and campervanners so know the camping scene well, we just need to get our heads around towing

Thanks, a similar level of thinking by the sounds of things. Ive seen a Bailey Orion 460/5 which is end bathroom but a side dinette at the rear on one side and a single bunk which could be level up as a double bunk on the other side. It means walking thru the rear bedroom to get to the bathroom but at least there are options for seating and getting up without having to re-construct seating areas. Ideally I dont want an awning, just a pull out canopy and windbreaker. The whole point of moving to a van is for an easy up easy down camp, otherwise i'd just buy a big inflatable tent with a hook up heater all pulled in a trailer!
