TL inverters are lower cost and higher efficiency, with the down side that that must have 600V isolation. It isn't just that the iso check is "annoying", if there is leakage once the contactors close, it's likely that you'll destroy the power stage.
No, we only do the Promaster van. We investigated the Sprinter, but it's heavier, has a lower cargo capacity, and would be much more expensive to convert. We have over 1 year engineering into the Promaster and are CARB approved. It's a professional OEM grade conversion, in fact, it's better than any of the OEM vans by far. We have shops that can do the conversion in LA, Seattle, and Minneapolis so far.
