Changed from 4x4 ute to 4x4 wagon, whilst i have more comfort, I have less space. So anyone come across or have a offroad camper trailer that has space for boards, sails etc without having to strap them to its roof. Ideally lightweight trailer for exploring remote spots.

Yep. Mine .Self built and features pullout kitchen, fridge ,60lt water tank, queen size bed. Carries 9 boards, 3 bikes and all the accessories needed for fun.

Cheap: I have a Kings rooftop tent and a separate Kings awning I wish to part with.
So a normal trailer, boards inside, mount the other thingies on it and you have a sub $2500 option (incl a brand new trailer that you can use for other stuff)

But if you want a camper trailer for true offroad, be very careful. So many so-called Aussie ones are assembled here from Chinese kits and they detonate on corrugations. Research lots and be prepared to really fork out.
