I dont know what kind of weight distibution hitch you are considering, but I will have to say that I use mine very rarely. My hitch mounts on the trailer tongue, and has two bars that hang pretty low to the ground. In rough ground(I dont know about you, but anytime I am hauling wood, i get into some pretty rough stuff) they are always hanging up on something. often enough sometimes that i get stuck and have to back up and try a different route. I found that I can haul just as much with out it for a short distance by centering my load on the axles, with the tongue just slightly heavier to maintain good control.
I rarely will travel more than 30 miles for wood in one direction, and found that the pain of hooking the thing up wasnt worth the effort for such a short trip.
Just my two cents worth.
