I bought a Bri-Mar dump about 3 years ago , it's 80" X 14' and rated at 12000 lbs. It has a twin telescoping cylinder set up with direct hook up. I have been able to dump every load so far ,some loads of top soil have been stacked high enough that it was falling off 3 sides ( I didn't leave my property loaded like that ) and still no problem dumping. It also has built in ramps , so I can haul my L-48 . A little extra length would be nice for the TBL but it works. Cost was somewhere around 6000
