Hi Neil,
No problem! Last year we spent 5 weeks travelling around the Highlands of Scotland, spending a week at each site.
Each time we moved camp, we used those lightweight storage boxes, which collapse flat when not in use, putting anything loose/breakable in those, wrapping anything fragile in bubblewrap, before striking camp. When we get to the next site, it doesn't take any time at all to put things back in place.
Another useful tip. Those bottle holders you get from the supermarket, with 6 pockets, come in very handy for holding all sorts of things. We usually put all shower room items like hairspray, shampoo etc., into one.
Remember always to put heaviest items over the axle or to the front of it. Heavy items put to the back of the caravan can cause the outfit to 'snake'.
