Yours sounds like a great application for a Lightning. Remember that the 9.6kW Pro Power Onboard that includes 240v in the bed is supposed to be available as an option on all models. It is unclear if it only comes with the Extended Range battery. At the Lightning event in DC, I was told the 9.6kW Pro Power Onboard was an option for the Standard Range battery as well. We will know for sure once the build & price tool comes out.
