While this subject is up, I'd like to second Dennis's comments, DON"T try to
run that inverter into the Westy 110 wiring!!

But, for using shore power, I found an easy way to access and still keep
from tripping over cords strung across the floor and all over.  I took a
power strip, like we all use at the work bench or behind the desk, that rats
nest that feeds all the computer related 'stuff', and plugged it into the
unused 110 VAC outlet in the wall outlet box under the sink.  For those that
missed it, the 110 VAC from outside the van comes to two outlets, the one
down by the floor where the breaker is and another buried under the sink
down inside the cabinet.  That's where the Dometic 'fridge plugs in and
get's it's 110 VAC.  Anyway, there is plenty of clearance at the back edge
of the cabinet, toward the driver seat, to run the cord from the power strip
back inside the cabinet and into the unused outlet.  Then I mounted the
powerstrip near the top of the sink cabinet (in my case I used double backed
tape, has held for over five years so far) behind the drivers seat.  Now,
when in a campground that has power, I have outlets for battery chargers,
cell phone chargers, laptops, TV sets, etc. AND they are all up forward, out
of the way NO WIRES TO TRIP OVER!  I leave this setup in place all the time,
out of the way, but there when needed.  And I can't remember the last time I
used the outlet down by the floor, next to the rear seat.
