I have a 47 COE and off-hand I recall the width between the dual rear wheels to be about 85-86 inches. That's too wide for a standard trailer (almost all trailers have a standard width axle) and the inside distance between fenders on most trailers is 83 inches. However, if you remove the outer two dual wheels, it should fit...or find a trailer with the bed mounted over-the-tires.
I'm at work and this is all from memory. I'll try to remember to check and post another answer if my memory is failing.
