I'm starting my research on dump trailers in anticipation of a purchase next spring and I have a few questions to start. Those of you who use dump trailers, are they deck over or low profile models. I can certainly see the advantage of a deck over model in that you can dump more out of the body before having to pull forward (i.e taller piles instead of longer piles). I use my trailer quite extensively for hauling and unloading mulch by hand rather than dumping. The low profile would definitely be better in this case. I will also be using the dump trailer for hauling my tractor around as well. As it stands now, the plan is a 14' long model.
