As I mentioned on another post, I had one, but 'dumped' it. Not because it was not a good product, but because I found it just too big and bulky. There are only 2 of us in te van and we tend to use site showers so the Waste Hog could sit for a week without getting full, and of course started to smell a bit. So I realised that we could easily live with a smaller unit and save a lot of space when travelling. Also my Thetford Loo has wheels of its own for the waste, so the shelf and straps were again superfluous to me. If you use the van showers a lot, and have a large storage area then it could be ideal for you.
