I have periodic need to have internal 115/120 Volt  power available
inside my van, and I always wind up have to string an extension cord,
leave a door or window cacked open for the cord access, etc. I'm
thinking of installing a 4 gang receptacle under the rear seat, with a
metal box under the seat and the receptacles themselves faceing out from
under the seat. It would be mounted on that board that makes for the
storage space under the seat. For wiring, a heavy cord would be wired
into the receptacle and strung through a hole in the slanted firewall
under the seat into the engine bay and  strung across the top of the
engine and the plug end would be tied off right at the rear service
hatch opening. This would allow for simply plugging in an extension
cable at the rear of the vehicle, eliminating all that other hassle.

Just wondering if there are opinions as to better arrangements, or
things to watch out for, cautions, etc.

Thanks,

Regards,
