Not sure what your towing with, but I have a 6x10 V-nose enclosed (3'v) and I can easily haul 3 bikes. Mine is standard height, many are 6" over, but I haul it with the Saab so the lower height makes it pull easier at 80 MPH
. Mine is from R&R (

Barber....................when is this anyway..........................twist my arm...............
Go for the torsion axle as opposed to leaf springs as they have inherent damping and sit lower. Brakes are a good idea if you travel at higher speeds as well.
If you are looking at an open trailer again I prefer aluminum trailers, Triton makes a good 3 rail, Worthington trailers are very well made too, but expensive.
