@MrWizard so I suppose the ideal solution would be to basically wait for a world where the cost/KWH of a Tesla battery drops to economical levels, and/or storage capacity rises to sufficient levels, for an RV that runs 100% on electric power. There might be a tiny diesel generator for backup power in boondocking mode, but the rig would be entirely electric otherwise. Thus, in this scenario, we can ditch almost all moving parts and use up that freed volume with more and more batteries (obviously placed along the platform).
Almost half the cost of a Tesla car goes to its battery, but hopefully some of the breakthroughs in battery technology might free us of internal combustion at some point.
