What kind of electrical receptacle do I use for my tow vehicle. I don't have the usual 5 point on the coach, I'm not sure what kind it is.
Can you give us a picture?
Usually, one can get an adapter that will allow the lead wiring for the tow to be connected to the motorhome plugin. These are usually available from a RV source. One plugs into what you have and provides a female to the towed vehicle wires.
this might be of help:

A few months ago, I got an adapter from Camping World that plugs into the round (5 or 7 pin) connector on the coach. The adapter then is the flat (4 or 5 pin) female connector to accept the (4 or 5 pin) plug from our tow dolly.
