I just looked at those trailers moments ago when I run across them on Craigs List. From what I can tell, they look like pretty good trailers. I have been looking at trailers for a while and have about decided I need something at least 20' and have been torn between the 10K and 12K trailers. I have pulled my tractor and a implement on a 7K 16' trailer for 10-15 miles and it is a little overloaded. A 10K would probably do, but was considering the 12K for a little more capacity. I also noticed in the pictures that there appeared to be a similar trailer beside it with the pipe rail sides. Thought that may also be worth considering to be able haul different loads easier. One other thought is the kicker ramps. I know they will be much easier to use than the stow away type, but also am afraid they may prevent a longer load, such as with a rotatry cutter on, from being able to hang off the back.
