Thanks for your replies!
I've read most stuff on www.windsurfwa.com, but I just thought that maybe some of the shops were specialized in 2:nd hand gear? Or maybe there were some shops which you guys personally recommend? Some of the shops must be bigger/better than others?

Any suggestions on where I should look for a 2:nd hand camper van in Perth? I gather Perth doesn't have a "Kings Crossing" like in Sydney?

2nd Wind has a huge range of second hand gear, most of which is on consignment.

Yes MacL3an, Geraldton gear is similar price to Perth.
Some used gear in the "buy and sell" forum on this site may suit. Most sellers will email photo's.

I have a campervan that may be suitable for you. 1990 MAZDA E2200 LWB DIESEL. Used it as a windsurfing van {until last year when I spoilt myself and upgraded!}, but I still have all of the interior cupboards/units for it. Haven't gotten around to selling it yet but had better soon as I think that my wife is ready to divorce me!{NO, REALLY!...selling it was part of the deal for getting the NEW van}.It has: GAS STOVE, SINK{with under-chassis water-tank and pump},3WAY FRIDGE {may need a re-gas as I haven't used it for about a year}, CUPBOARDS, OVER-CAB SHELVING, DINING TABLE{small one that connects to rear door}, SEATS/2 BERTHS WITH MATTRESSES, EXTERNAL POWER{ie you can pull up to a caravan park and "plug in"},EXTRA INTERIOR LIGHTS, SAFETY SWITCH{circuit breaker}, SLIDING WINDOWS WITH FLYSCREENS, WINDOW TINT, CURTAINS, ROOF VENTS, REAR STEP AND BARWORK, ROOBAR.
It's a hightop, so at 5'6" I can stand up in it without bending{maybe not so good for you!!}. It has a bit of rust around the window inserts but nothing structural. NOT the FASTEST or funkiest van on the road but it's been ultra-reliable and comfortable in the 8 years that I've had it. Put a new heavy-duty battery in last year.
Spent AUD$1500 on her 3 yrs ago, have receipts .
Don't know if it's what you had in mind or not.
