For this reason the smaller the trailer the better. Go with the Torsion Tube type axle. You'll get a lower trailer height, which helps with the handing. If the trailer starts to sway on you, just a little tap of the trailer brake control will help bring it right back into line. Check with local regulations to see what is required.
Fenders have a bad habit of falling off.
I prefer tail lights to be mounted up, by the fenders, as low slung ones under the trailer seem to get removed by ramps leading into the Motel 6 all to often. We chose these types of supports which allow for easy adjustments. The stantion simply slides through the piece of box steel with a hole drilled through it for a bolt to slide through. It is nice to have room to secure that extra ice cooler, awning, tent, etc. while traveling to a show. Maybe even a small removable carrier to be removed at the shows, and stashed inside your tent once you arrive.
