Ok guys here is a finder for Leviton all your hardware stores will have it.

they have shore power inlets for 120v and will be cheaper than Bass Pro.
This is the way I am going to wire mine. I am not an electrician so take if for what it is worth.
Wire as follows:
if 15 amp use 14g or 12g
black to gold (or brass)
white to silver
green to ground (screw color going to round plug) romex has bare ground.
if 20 amp use 12g wire
if 30 amp use 10g wire
Inlets come rated for amps.
The Zepher has a good picture and diagram of this. The others do as well.
If this doesn't make sense to you don't do it. Hire an electrician. It really isn't worth the problems to do it yourself
and is dangerous.
I don't know how to wire to a converter, sorry.
