congrats, I recently bought a bri mar 7x14hd dump trailer and it has a gvw of 14k but i've had it loaded with 8 yards of process gravel and it dumped it fine. dual piston, just gotta make sure the battery is charged, it has marine deep cycle and I need to pull it out to charge it overnight every 6 months....not bad if you ask me. what kind of axles does the trailer have? my bri mar has dexter axles and bucher hydraulics, some of the best out there. it also could be built better, but i overload mine all the time...
