After about a year and a half of procrastination, I *finally* got off my butt and ran wiring to the bed to provide power for a 12v outlet to run my fridge. I modeled my install after a post on the tacomaworld.com forum with minor modifications.
At the advice of JR and Aaron K., I opted to run 8ga wire, with a 40a circuit breaker under the hood near the battery connection. I ran both hot and ground inside split loom from the battery on the drivers side front corner, along the top of the firewall, down the inside fender to the frame, where I followed an existing run which I believe is for the 110v AC outlet in the bed.
Unlike the tacomaworld post, I put the panel and a combination 12v / USB / Voltage Meter in the door of one if the side pockets adjacent to the 110v AC outlet. I hardly use the pockets, and that's a cheap replaceable part if for some reason I need to revert to stock-ish form. The 8ga wire terminates in a bluesea 6 fuse panel which feeds the devices, and hopefully soon will power my canopy LED which the installers ran all the way to the battery (poorly too...).
In addition I added a 6 fuse panel in the engine compartment which will provide fused power for my CB and new Kenwood dual band radio. This will be a nice change as for almost 4 years I've powered my CB from the 12v lighter in the cab and there's a HORRIBLE noise from just about anything I run (windows, windsheild wipers, and the electric power brake booster which kicks every 3rd or 4th time I use the brakes).
I'm happy that I now will be able to leave the fridge in the bed while camping instead of taking it out to hook to my battery directly at night and looking forsward to the cleaner groud near the battery reducting or eliminating interferance.
