400 mile electric RV

400 miles. BUT, THEY HAVE NOT ADDED HUNDREDS OR THOUSANDS OF POUNDS OF WEIGHT. They state "renderings" of what will make it a RV. They just have a body and drivetrain now. What happens to the 400 miles when you have the FULL BLOWN RV version? Is it going to be all electric or will it have LP appliances? ALL ELECTRIC means a drastic reduction in that 400 miles. How is it going to be Cooled? That will be a very hot box if no AC system. Water tanks and holding tanks. These add weight and decrease mileage. Me thinks this is a premature press release to try and gin up enthusiasm. They do not have a actual vehicle to be evaluated yet. Doug

I think you're underestimating how large the battery would be to support that range.

The chassis they are basing it on has a 175KWh battery for 150 mile range, so presumably it's going to have a 400KWh or larger battery for 400 miles of range. They quote a "laden" range, so presumably have already taken into account weight, but I don't think weight is the largest factor in the range of an EV (you need more energy to get up a hill, but you recover much of it on the way down the other side), it's more the wind resistance.

That 400KWh battery pack is more electricity than my home uses in a month. A week's worth of cooking would have a negligible effect on range, an hour a day of a 1500W microwave and 1500W stove, would use 21KWh in a week, about 5% of the battery. Even running a 2KW air conditioner for 8 hours a day every day would use only around 112 KWh in a week, or 1/4 of the battery.

It'd be pretty affordable to operate, It would cost me less than $50 to charge that battery pack at home, a small class C with 18mpg gas mileage would use around $77 of fuel @ $3.50/gallon.

But I suspect that most people that buy what will certainly be high 6 figures if not $1M+ RV are going to take it to an RV park where they can plug in and charge the RV.
