I've bought a camper van!

So after so many hours looking and what felt like constantly being to late to the party as vans were sold so quickly, fate was finally on my side and I have paid my deposit. The word excited doesn't even scratch the surface!!
I've got (will have in a few weeks) an Auto Sleeper Symbol / Orian Pavo 2007. So a few questions from me:
1) is it worth getting the extended warranty - £500 for another 18mths on top of the 6 myths it will come with?
2) any recommendations for insurance companies
3) I want to get the Gaslow refillable system fitted (not by my dealer as they were quoting way too much). I can fit a 6Kg plus a 2.7kg bottle do I need both or will 6kg be fine providing I keep it topped up?
4) what are your recommendations for mattress toppers - i.e ones that aren't too big that they take up all the space in the overhead cab storage
Finally .... for now!
5) what are your top 3 accessory recommendations

I'm sooo happy to be able to join this community properly now I will be officially on the road.

PS - 20 years ago I drove to Australia across Iran / Pakistan / India etc in a Landrover - I loved the Landy but this is going to be like travelling in the Campervan equivalent of the Ritz!

Welcome, Froggers!

1) re warranty - probably not, because of the mythical myth-ness they come surrounded by

3) re gas, is an underslung tank an option for you instead of bottles?

4) I bought a generic 2" memory foam topper from ebay and cut it to shape.  At which point I then found out just how big 2" foam is when rolled up!  That's now in the loft. I then bought a 1" generic foam topper from eBay and cut that to shape.  It takes up less space, but is still surprisingly large!

5) re accessories - Levelling ramps, security devices, "proper" plates, mugs and cutlery, ie. The regular type you'd use at home, not the camping variety

I go along with RogerThat, 

Wouldnt consider the extended warranty as they tend to have get out clauses hidden.

Think current Symbols have underslung tanks (GasIt) so if you went down that route it would save you space in the van.

I personally prefer sleeping bags to Duvalays, and the latter does take up more room. Management has one and it has to travel on a seat and when parked up on a cab seat, whereas my sleeping bag will go in the overcab space.

Levelling Ramps,  Fresh Water Container, Toilet Chemicals.

Try sleeping in the van before you splash out on mattress toppers etc. Our van's very comfortable without additional layers, although my wife insists on using a domestic mattress protector (of the sort you can get in Dunelm Mill). I'm not convinced it makes any difference.  

Accessories? don't overload with clutter! levelling ramps, EHU cable (plus adaptors for domestic/European sockets), food grade plastic pipe for filling water tank + assorted tap adaptors (mostly we just use a plastic watering can).  We are happy with the melamine camping crockery - much lighter than ceramic and more durable (the ceramic stuff doesn't bounce) - although the mugs stain fairly rapidly.

Take a few essentials, book yourself onto a site that isn't too remote and go out and enjoy your new van! Adding more clutter can come later.

Thanks so much for your replies and great advice - will definitely spend a couple of nights in her (have already decided its a she and her name id Shirley!).

I have told the dealer that I won't bother with the extended warranty. 

So looking forward to getting her and will just gradually work out how much space I have and what I need - but EHU / Water etc will be in the essentials pile!

Thanks again
