I did one of these trailers. It was expertly packed in two boxes with lots of form fitted padding. It does indeed go together quite easily but even so it will take several hours to assemble it due to the number of pieces. You MUST tighten the nuts down hard once you have it all together or it will fall apart from road vibration. Really crank the wrench. The axles are not greased, something I failed to notice. Make sure you pump them full of grease. The bunks are fully adjustable since the whole frame is built from channeled aluminum. It is very light and I use it as a dolly to move my kayak around the yard and sometimes at the boat ramp if it is busy with full-sized powered boats. The company is very helpful, they replaced a bunker and a tie-down bracket that I lost before they told me to crank down on the wrench. Be advised, if you live in Pennsylvania (and other states I am fairly sure), you will spend several hundred dollars getting a title and registering this trailer. That part was a nightmare and it was ridiculously expensive. But I love this trailer. I have had it almost two years now and have had no problems after retightening all the nuts and bolts. Yes, I have pointed that issue out three time now.
