I would spend a bit extra and put a hydraulic lift on whichever trailer I were to buy. That being said, I would still prefer a gooseneck for the added stability. I use both frequently. We have a two horse bumper pull, that we pull with our towing vehicle (on local runs), and a four horse living quarters gooseneck for showing/camping. The two horse is easily forgotten when we are driving. It is barely enough weight to keep the rear end of the truck from bouncing as if unloaded. I still prefer pulling the gooseneck for any long distance. It pulls better, backs better and except for local use narrow roads, is far superior with regards to the 'ride of the load'. The bumper pull is much better for the local runs, as it tracks closer to the path of the towing vehicle. I can back the bumper pull into tighter spots, with much less room required, but I have to change 'gears', every time I back it. The turning radius is so much smaller, that I find myself backing like a drunken sailor with the bumper pull.
For me the turning radius requirements would be the decision maker. Especially if I were to have to deliver to unknown addresses (don't know how much room I would have to back/turn for putting the firewood where the customer wants it).
Best of luck, you seem to have conquered the big problems, like heavy axles, dump bed, a decent tow vehicle. No matter which way you go, you will find instances where you wished you had made the decision for the other option.
