On a smaller pull behind, such as a 18-20ft, whats the advantage of a tandem axle versus a single axle?

I could write a book on advantages for a tandem axle advantages over any single axle on a 18'-20' trailer.

Having pulled both for a living you could not pay me double contract wages to pull a single axle trailer. JMHO
