I put them both on the forward trailer to lighten up the back as much as possible (you don't want the tail to wag the dog). You have to plan ahead to go into gas stations and such. Corners did pretty well, much better than if it was one trailer with the same overall length as the two combined. I actually forgot the extra one was back there when going down the interstate. One key thing is to make sure the hitch for the back one keeps the toung up a little, it tracks better. I simply used a reciever drop hitch upside down. Phillip Mumm has some pics of it, maybe he'll post them.
