My wife saw a device in a garden catalogue called the Load Handler which is
supposed to turn your pickup truck into a dump truck. Essentially, it is a
tough sheet of fabric which you put down in your truck bed and dump your
load of mulch, gravel, whatever on top of it. To unload, you drop the
tailgate and turn a crank which rolls the sheet to the back of the truck,
pulling the load along with it.

For $150, it seems too good to really work as advertised. I wondered if
anyone has tried one of these and how you liked it. Details can be found at

I just posted their website for general information; I'm not affiliated with
the Load Handler people, just thinking of buying one if they really work.

Just to come back on this old post. There are now many references to the Loadhandler system on the web. Over 600,000 units have been sold in the USA. Many think it's a fantastic bit of kit. It's now in the UK with a Loadhandler dedicated UK site. Just for your info.
