Inverter wiring
Picked up a 2Kw inverter. This will only be used for occasional remote power, short periods of run time. No plans to idle the truck for long periods.
2000÷12÷.9=185 amps. A voltage drop calculator suggests 4/0 to keep the voltage drop to 3.4%.
The truck has dual batteries and alternators. My idea is to run a #1 cable from each battery to a 200 amp breaker under the hood and two #1's to the inverter. The cables will be the same length. Parallel #1's to the frame for a ground. This way the Hall Effect devices on the batteries can monitor what's going on.
I'm assuming I will also need to upsize the factory frame to battery negative cables to handle the additional load.
Yes a generator would be easier but I don't want to carry one around.
Thoughts?

These trucks are sooooooooo amp and voltage sensitive that I would not do what you are talking about.
I would say you would be better off with a pair of extra dedicated extra batteries to run the inverter and a charge wire run to the 12v pole on the RV plug.
Or get a 2KW inverter generator, they are small and don't use much gas, and can be found on sale for $400 or less.

Skip all that and get one of these. 27lbs. 1,800 watts continuous and 2,200 watts surge. You can expand with a battery for more run time. Use it at home, on the job, camping, etc.
