Just a note... a person with a pair of wire cutters and a spare 3-prong power cord need not buy anything at all.
I took an older computer power cable, cut it off a few inches from the 3-prong connector, spliced the neutral and ground together, then tied the wires off with wire caps and wrapped it all in tape so nothing would come apart.
Hooked up my 2 Honda generators to the trailer for the first time yesterday, worked like a charm.
I love turning gasoline into cold air... :P
