Thanks Al!
the picture makes the wiring look all wiggly waggly but I promise that was just the shape of the truck. Bothered the hell out of me looking at the pictures tho.
I sat down and compared a BUNCH of inverters in the the 800-1000W range this weekend. I settled on the 800W Cobra; it should be here on Wednesday then it is time to go get busy installing it. and yes, I will take LOTS of pictures.
Sometime in the future I will run another larger gauge wire to the trunk dedicated to the audio system but for now, I have a 4 AWG ran from front to back for the trailer and rack lights; this should be sufficient for the relatively small inverter.
