It comes down to this. The truck has receptacles, and as such, it is considered a portable generator per OSHA. This means the receptacles will need to have the neutral bonded to the ground for short-circuit protection. The issue is if you open this bond (which you will want to do for home power), then when you use the truck as a portable generator, it would be unsafe as it needs to have the neutral and grounded bonded once again. In portable generators (gas-powered) there are plugs you can buy that have the ground and neutral tied together in the plug. This way, you can leave the neutral unbounded for home power and use the plug when using the generator for portable power. I have yet to see the drawings for the inverter in the Lightning but will have one here for use in the next month. Here is the OSHA guideline that explains the risks. OSHA generator safety
