I somewhat agree. But not necessarily battery density, more of range and charging time. It may work for those that don't drive long distance but for those that do will be impacted but those charge times.

From what I understand you can't put in a larger battery system, if you could it would take up the payload and space.

Battery chemistry is under going a lot of development but fast charging equals a lot of heat.

EV = Battery weight/size and energy storage along with charging time and the percent of usable capacity along with any considerations of heat buildup and cycle counts. Keep hearing of all many related breakthroughs with little tangible results.

Seems any discussion of battery density/tech/charging is all under the EV powertrain.

Comparisons to ICE are logical for most of market. Why spend more to have too many compromises, otherwise EV is no more than an option, not a direct replacement.

To meet a broader spectrum of use, must meet current broad spectrum overall effectiveness and ease of use.

If not, will remain narrow spectrum.

The next generation of batteries has been in the works for a few years.

This EV is not going very far. 120 kwh was the largest battery I saw spec'd. That is roughly 4 gallons of diesel or 3 1/2 of gasoline. What they can do with that little amount of fuel is amazing but it is not magic.

It looks like it will have a nich for city box truck drlivery. Maybe after they develop experience, new designs, technogly breakthroughs and battery improvement it will be ready for MH's. Im betting it will be a decaid or more.

Here's one available now based on the GM electric van. Only $195,000

I'd love to see a real world test instead of promotional propaganda. It has a smaller battery than the other GM EVs, yet claims a longer range. That should raise some big red flags. They are also claiming that solar panels extend the range. We know solar panel output is not in the same category as the energy needed to power a vehicle. Compare that to any solar powered car. Those cars are always hyper-aerodynamic, and usually have a top speed limit of 20 or 30 mph. That should be a clue as to how much energy can be collected form solar panels.

The interior reminds me of my avocado green 1976 Tioga, lol.

I went back to look at how ugly the green interior really was, and noticed the solar panel is rated at only 650 watts. That is less than 1 HP! Someone explain to me how adding 1 HP additional power to a vehicle is going to ad another 100 miles over the original 150 miles that GM is advertising. While environmentalist often stretch the truth optimistically, this is just flat out lying.


Truthfully the PebbleFlow makes a little more sense, as it turns your towing capability into a hybrid. That could have some benefit, except in the Midwest where everything is flat. Might also be something interesting for Radar to use on the back of his Tesla.

While I agree that the touted specs for this EV based MoHo are a bit , um, optimistic, I feel that it's easier to control the unknows with an entirely enclosed one piece unot vs an EV trailer that can run behind various vehicles, shapes and sizes.

It's a bread box, maybe a wee bit more aerodynamic up front, but still a box. They at least know the dimensions and Cx. so much of the variables are accounted for.

They don't "need" a huge motor to drive it. I'm pretty sure even the drivetrain from a Bolt could power it as long as GVWR remains under 10 000lb or so. It wouldn't be a rocketship, but RVs rarely are.

With a smaller powertrain and 170kWh+ battery, I suspect 350km range is not impossible. Charging doesn't require 350kW units either. Heck, I'm sure a campground's 50A site running an onboard level 2 charger would charge this in 12-14h. Arriving at 6PM or so, it'd be ready with a full charge by 8Am next day.

No one said the 640w solar panels would be useful for rechargingm they even mention plugging it in is the recommended method. It "could" add range for someone parked in constant sunlight and boondocking for weeks in one spot. Sometimes that's all you need to get to another charging station or campground.

I agree kdauto. Today my Silverado has 350HP and still slows on a long steep hill. Then I look at my 1932 Chevy with the stovebolt 6 @ 85HP climbing the same hill, I must use 2 gear to get to the top.
My how things improve with time and engineering. Some of the new battery technology is very promising:https://www.gridtential.com/ https://webstore.totalbattery.com/category-s/2147.htm are just two.

My wife (being from Norway) was reading some Norwegian news this morning about the problems with the electric city buses in Oslo last Winter. Sounds like they might be going back to diesel, but there's always the hold-outs with work-arounds. Like putting diesel heaters in the buses and keeping them plugged in longer, and having shorter runs in the Winter.

Some of the surrounding towns are giving the E-busses a second thought also after the fiasco durring last Winter.

One person commented that the articulated buses struggling to get around in the snow were like having your engine on a trailer behind you, and expecting to get around in the snow.

Here's one report I could find in english.....https://www.euronews.com/my-europe/2...ue-to-the-cold

So maybe there's more inovation required before we can expect an E-MH of any size.

Bah, early adoption woes. Not sure who they used for the EV buses, we have several around here. Automotive figured out cold and heat really affect batteries, so they're all temperature regulated now. I guess some of the heavier vehicles maybe didn't get that far yet?

As with anything, there will be a learning curve. There may be some situations where EV just isn't worthwhile and it may cause headaches along the way.
