Hi. Picked up my new Cali SE in late August. It's hard to resist the temptation to kit it out with lots of stuff! Essential purchases will, I'm sure, vary from person to person. Apart from basic crockery, cutlery and a couple of pans, for me (dog owner) essential have been:
* seat covers
* floor carpets (Brandrup)
* mattress cover (4-foot fitted sheet does the job perfectly)
* hook-up cable
* Porta potti (for me, not the dog!)
* storage containers to organise the boot and the kitchen unit (I got 6 inexpensive washing up bowls)
* after a bit of detective work, an 'Osprey Airporter' (a large, strong zip-up bag for transporting rucksacks in the hold when flying) into which I can stash a duvet, pillows and fleece blanket
* and, from a review here, a great bit of kit, an over-the-kitchen-unit shelf from Calitop in Germany to keep all those essential bits and bobs (glasses, keys, book, and so on) in one place - the best bit being it that it just slots into place - no drilling of the precious new purchase needed! (

I hope you enjoy your new Cali as much as I'm enjoying mine.
