I'm not sure how long, but I'd guess around 15 feet or so. I can tell you that loading it on a trailer is no problem. If you have a long bed truck you can even load it in the back of it, tie it down, and attach a red flag since it'll stick out a ways.
It's not that heavy at all and you'll probably be shocked at how light the frame is. You could lay it beside your trailer, pick up one end and load it on, then do the other end, all by yourself I bet. I've loaded mine that way twice.
Right now I have a spare rearend loosely bolted to it and when I need to move it, I grab it by the front frame horns and push it like a wheel barrow. It's not any harder than pushing a wheel barrow load of firewood. Good luck with it.
