Walco imports a lightweight 2000 lb capacity dump trailer that's 44" X 84". Its sides and/or tailgate fold down.
I bought mine from Lucas Distributing - 613-254-6599, northwest of Ottawa, Ontario. It cost about $1700 new.
While it initially seemed fragile to me, it handles work around my property quite well. Its narrow width is useful in the bush and around rows of trees. This type of trailer cannot be towed faster than tractor speeds, though I have walked it two miles to a vendor for a yard of gravel a couple of times and it handled the job just fine. The folding sides are great for loading block wood by hand and sliding each block off at the right height for the splitter. The folding sides get used more than the hoist.
