solar powered camper up to 450 mile range

Neat project. But - RV life as it is with conventional ICE's already has it's share of concessions and contingencies including redundant power systems. Even with today's concessions you can run til near out of fuel, fuel up in a few minutes and be off. These EV's are nothing but concessions. The full focus is EV/Solar power and everything else - time, comfort, travel habits, destination planning - everything - takes a back seat (pardon the pun) to the method of power and all the limits and compensations it brings. Which is the total opposite of what RV life is supposed to be about - the total comforts of home anywhere and anytime you want. I won't touch on the debate about what problems these vehicles actually solve (or don't solve) in terms of ecological benefits. I just can't see me camping in that thing and enjoying it despite whatever claimed benefit it's supposed to have over today's efficient ICE's.
