No argument from me. When I was in school, the mechanical engineering department worked on various electric and hybrid car and bus projects, and the greatest challenge was getting range out of lead-acid batteries (yeah, that was many decades ago). Drive motors were relatively easy. Decades later, battery energy capacity remains the main issue even though it’s about 10 times better.

For an Axis like yours, you need an average of around 100 HP to cruise down the road at highway speeds, so you’d need close to 100 kW-hour of battery for every hour of driving. As we’ve discussed in other threads, cost is probably no longer the main challenge, but weight of +/- 500 kW-hour of batteries could weigh down a compact motorhome the size of Axis. Not that cost isn’t an issue still.
