I have a 14 foot one w/ a sissor hoist, best thing in the world. I use it for a dumpster on jobs and haul soil, dirt and anything else. It's a 2006 and I got it about a year ago for only $4,600. It was barely used for Katrina clean up and then sold to me
I found it on craigslist about 3 hrs away in Conn, well worth the trip.
I put 2 foot high wooden wall extensions so I have about 14 cubic feet of cargo space .
I have to echo what others said about the cons of having a dump truck, the cost of insuring, registration & the hassel of inspection really kill any pros to a dump truck, especially for occasional users.
