My wife recently bought me a new trailer and I've got a question or two you all can probably help with. The trailer is a Load Trail 20' car hauler. It's a bit bigger than I need right now, but she is such a sweetheart, I couldn't turn it down. Q1, I was taught to always load a trailer hooked up to the vehicle, but with the knee-ramps, do I still need to if I chock the wheels so the trailer doesn't move? Q2, After looking at the Wisconsin DOT website and coming away more confused than before I started, I am wondering if I need to license this trailer? I e-mailed the DOT but I figured you guys might know as well. By the way, I'll be hauling my JD 4310 w/FEL and usually a mower or tiller. JP.
