If you are referring to the 'Waste Hog' trade item then I sympathise. I was 'persuaded' by my own indulgence to buy one of these at a caravan show and have regretted it. The item is itself very useful and does its job fine, but is very bulky. I was even persuaded (by me I may add) to buy a storage bag, which made no difference to its bulk. I stored it initially under the fixed bed, but found getting it in and out was diabolical. I have since disposed of it on a 'dump' and will be buying a jerrycan type of waste container that I can easily store and use. Yes, I will carry it instead of wheeling it, but the extra space released is far more beneficial.
My conclusion? Sometimes we can get ahead of ourselves, and reality when let loose in an accesory shop.
