When Sportsmobile builds a class b motorhome, dc/ac fridges come standard in the pricing. Propane is an option. Sportsmobile tends to build for people who want to get off the beaten track. Often times parking at trailheads is not level. Dc (compressor style) fridges will work at angles up to 30% . Propane fridges will not opperate too far off level. This matters if you go on an all day or overnight hike. Many SMB 'S Have no propane at all,utilizing big batteries,solar,power,inverters to run hot water heaters, microwaves etc... They were making all electric campers long before Roadtrek got in the act. They also use flatplate waterheaters and other devices.
SMB has a YouTube vid of a demonstration of an all-diesel Sprinter. The stove is a Webasto, the furnace is an Espar model, the water heater a flat plate diesel version, and it can also have a PowerTech generator added, so there is no need for propane whatsoever. You do pay a price premium for these things, but it gives you virtually the same functionality as an E-Trek, except without the heated floors and other niceties. Plus, with a decent battery bank and inverter, it will run a compressor fridge without issue.
