I've picked up a second hand 7x4 load star trailer that is rubber lined.Overall pretty good condition, licenced, put a couple of LED's on it, need to do the wheel bearings and only paid $600.
I'm now going to get a 7x4 tent and just bolt that on when we go away.

Prob end up putting some bigger wheels and jerry can holders etc on it. If we use it alot, I'll trade it in on a conqueror for sure. Saw one today being towed along.....just about spun my neck off my shoulders looking at it!

Thanks for the helpfull hints, I'll post some pics up when its ready to roll.
