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.

Don't get me wrong I think electric RV's will happen I am just skeptical it will be very soon. I would be surprised to see any widespread production ones in the next 10 years. I would be glad to be proven wrong. Long distance highway travel for a large vehicle is the most extreme application of an electric vehicle due to battery cost and weight. The Tesla semi is boggling in the numbers, megawatt hour batteries, megawatt chargers, 4 motors at 1000hp / 2000lb-ft of torque. I am very skeptical they can pull it off at the costs they are claiming without losing money on it, again hope to be proven wrong.

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.

Thinking about an RV with Tesla semi size battery though that gives me goosebumps. Run the a/c offgrid for almost a month! No generator noise. Slow charge off solar, or any wall plug you can find. Won't get you far but maybe enough to get to a real charger. Truly all electric setup, will be fun.
