Right now I have an 97 7or 8X12 dump truck. I was thinking about getting a dump trailer but I like how we can put one guy in the dump truck pushing mulch into the wheel barrel. He can fill one in about 30 sec. I went to go look at trailers today and I don't think this can happen with the high when it is lifted to let gravity do most of the work. The only thing I can come up with is if I get one with a dump and spread gate (not the barn door). and use the chains to left it to the correct level to get in the wheel barrel. Am I over thinking this we do a ton of mulch for my size operation.
