We are a family, 2 adults, 10,6,3 yo kids ,this is how we load our swan, ours is a 2003 model, I don't know how much different yours will be
We use the front lounge space(under) for spare blankets and towels, also a bathroom type heater is also stored there for winter nights (powered site)
The cupboard/draws to the right of the entry door is for food, cooking condiments, utensils, torches, plates, cups, mugs, and condiments, the reason for that is for access with out opening the whole show up, able to do food stock take and or loading/reloading before a trip, and all reachable without climbing into the van during camps, handy also for roadside lunch stops.
Slide out draw under seat in dining (forward) area contains fry pans, saucepans, the mesh open fire toaster, first aid box, rearward contains Tupperware, extra jackets for real cold stuff also goes in there.
Stand up cupboard we use for clothes, I made shelves for that, much more useful than it being for hanging space, beneath that goes, battery lantern, toilet rolls, paper rolls, spare toilet chemical for the port a potty, big dolphin type torch and a few other bits and pieces.
beneath the sink goes the electric toaster, plastic containers with a host of other camping stuff like matches, dish washing stuff, large stewing pot, tea towels are in the draw just forward of the sink, there is a useless sort of a draw that hasn't got anything in it.
I have a large battery, charge controller, car type radio/stereo, plus power converter in forward of the fridge beneath the wrap around lounge on the driver side of van (if that makes sense).
I have a large folding camp table and 2 folding bench seats that get tied down on the roof rack of the cruiser, we nearly always eat outside under annex, and we also cook meat and bacon outside so it doesn't splatter fat up the canvas walls inside.
The previous owner fitted some 100 mm PVC pipe on the draw bar right across the front of the van for storage of annex poles and also for the poles that go on for the bag end fly's, also a drain pipe for the sink gets folded into half also goes in there.
My model has a big front boot, water hose, power leads, 2nd gas stove, heaps of stuff goes in there, must take charge of that one day, probably stuff in there I didn't know I had.
With this loaded in this way, with 2 9KG gas bottles, full tank of water pretty much loaded to go, it has about 220-250 kg ball weight.
