That's the Crump and Cornish trailer. Body is all aluminium like the RAAF no. 5's. Same as the one I have! Would go well behind one of your 6x6's mate. That's cheap if it hasn't got any major issues, I think I paid nearly 2K for mine some years ago. They are a bigger tray than the no.5 have a drop down tailgate and rear fold down stabiliser legs as well as braked. Snap it up!!!!
