Tony, there's an RCU thread on trailers still active. Here is the link

I bought a 5 x 10 trailer (CM Trailers) a couple of years ago. Its worked out well for me. Its set up to carry two GS warbirds, a couple of smaller warbirds, and field equipment. I recommend a front door and torsion bar suspension.
