fair enough. The numbers are probably right. Good to have a baseline as it will just improve from here. Battery cost needs to keep declining along with energy density. We are not at the end of the curve yet IMO.

I used to think how great it would be if an RV was setup like a diesel electric train, maybe multiple generators for redundancy etc. But once you do the math you realize how that just not feasible. Trains and some boats do it for specific reasons while accepting the downsides. Those downsides are just too great for weight and size constrained road vehicles.

I still think a plug-in hybrid system could work great in a large RV. Get rid of the transmission and all the related issues and service. Electric only would power the MH to about 45 mph and then the ICE would have a single clutch to direct connect for highway travel. Maybe 200hp diesel and 300hp electric to work together climbing hills etc. Maybe 50 mile electric range with the ICE generating power if needed. Just something to give balance until technology is able to go full EV at a reasonable price.
