A fair bit of stuff there, a few years back they were clearing out some similar campers, I went up and had a look at some but the prices they ended up going for, and what they needed to be finished/repaired meant the buyers wouldn't be any better off, and thats before taking into account no warranty, their time and effort to fix them and the fact that most of them had some wear and tear that wasn't really repairable.
Will be interesting to watch, the smart money is on some bidders getting auction fever and not many bargains to be had, but with the volume of stuff their might still be a few.
