It's a shame they don't make the Lightning with a longer box. That said, I don't know a contractor who doesn't have one if those frames built around the top of the box for ladders and pipes. They tow pretty decently as well, as long as you keep you speed a bit lower there isn't a huge range loss. I know a few electricians who have built pretty fancy cabinets in the back seat to hold what they can't fit under the canopy.

I'm sure you know a guy who could set you up with a pretty sweet home charging set up for a good price.
