You have an unworkable parameter in your list (at least in my opinion). You need to seperate the "I use this truck for my dating lifestyle’ and the “I want want a truck that makes (and does not take) me money”. OK with that being said I would not think about dumping the seperate generator for even a second. For one you don’t want your truck down due to issues with the inverter,stay seperate and even plan on getting a backup generator.
Make a plan and list features that are most helpful in helping your business, only.
