Ya, I'm just an electrical freak. I should have been an electrician! I'm always pulling something or running some thing off the truck, so just want to make sure I have enough to run everything including charging the fiver when towing. I know all the rant about the wiring being to small to take advantage of the 440 amps. If so I'll run a heavier wire to the plug and upgrade the camper, trailer as well. Nothing wrong with BOMBing the electrical system along with the power of these things!
