Ekomotorhomes new class b based on Dodge promaster

This unit and the travato both have the 110v only HWH. I don't understand the thinking. For those who do alot of dry camping it just doesn't make sense. I was inside the travato at the hershey show and there was certainly space to put an gas/electric HWH.
I am not sure how you were able to tell which composting toilet eko is using since the photograph of the bathroom on their website is of a casette toilet. The promaster platform certainly looks like it will afford some new and interesting b class options
