I really like the B-wise dumps I've seen, probably the best fit and finish I've seen on a trailer in person.
I pull a 16ft deck over tag trailer with a my 07 2500 ram, I like the larger size when hauling brush or mulch, it is easy to overload with heavier stuff.
I was taking some of the fill I created from my new shop over to my my neighbor, wet clay, thought my skid steer had a smaller volume bucket then it did. Estimated about 10-12k lbs, actual was 16-18k lbs load, oops! Still looked like a small load.
