Fursday Thursday - Insider Tips Anyone?

Now that I've realised we actually need to start thinking seriously about the rally and what we need I've started thinking about Constance and how to make her habitable for the course of 17 days! She not being very big, us not being very good at packing light we're going to have to plan how we pack our car with military precision and if Pimp My Ride can deck out cars to be entertainment systems and party vans with margarita makers, TV screens, garbage disposal units and mood lighting then I think with a few minor adjustments we could make Connie a real home-away-from-home, for the duration of the rally at least.

Basic must haves that I can think of so far are...(this list is far from exhaustive - any ideas anyone?):

1) Collection of plastic bags for rubbish. Luckily, I can fold plastic bags into neat little triangles so we can have loads of these.
2) Cooler box spot. I think this is integral to a pleasant journey in general. If we can make the cooler box part of the decor then I think we'll have not only a source for our treats (read gin) but potentially also, a table, head rest, seat for George Monkey, deadly weapon....
3) Map Spot. We need to make a little home for the map which is nice and easily accesible. Being lost is stressful, being lost and not able to find the map because someone's sitting on it or thrown out is the stuff of angry words, and no one wants that.
4) Home for loo roll. In an earlier post I made mention of peeing in the wild and how, to add a modicum of decency to an otherwise fairly distressing endeavour, a little bit of loo roll goes a long way. If we can create some sort of structure, perhaps connected to the cooler box, which would hold our loo roll out of the way but within reach at all times we'll be both happier and less likely to discover we've stood on our last bit of loo roll and there's another 10 hours to civilisation. Perhaps this structure might also be able to support other things. If we're really clever we could attach a line to it and create some sort of washing line perhapsd, or a pulley system for moving our sweets from driver to back seat without any over-arm stretching...or am I going too far now.
5) Actually, maybe this is too far, although how awesome would this be:

Any other top tips anyone?
