You know, with a larger battery deployment, making thermal management for the battery pack(s) becomes mandatory......just ask Nissan. I hope they have taken that into account. Tesla and GM have for sure...pretty sure Ford has too....basically anyone with a larger battery back has to deal with keeping those batteries at a reasonable temp. Too hot, cooks the battery, too cold, battery efficiency goes through the floor. Needs to be like Goldilocks...just right for longevity of the pack(s). At $150-$200/KwH, you don't want a $1500 replacement cost in year 2 or 3, let alone any labor costs extracting the battery pack(s) if they are not smartly installed.

But overall this is encouraging news. Very encouraging to see them make a point to talk about boondocking too!

Now, which dealership have we seen recently with a very similar setup? I'll give you a few minutes. LOL

The powertrain expertise is brought by ZF, who did the EV powertrain for a Mercedes SUV that is in production. While Airstream would have little experience with battery heat management, ZF does.

I am impressed that they don't just mention electric assist. The details include

* Remote unhitched trailer movement with a handheld controller, for parking
* Trailer to house connectivity for backup during power outages
* Electronic stability control using trailer wheel motors
* Voice control (Alexa, do I still need a WD hitch?)

and so on.

This thread is about the eStream trailer, but they showed an electric motorhome as well.

Looks like Thor is going to help the EV movement!

I am looking forward to seeing more developments. Charge the trailer and the Tesla at the same time.

Yes, but this is the concept vehicle. Previous test vehicles have been smaller and lighter. This is the first Airstream configuration. No reason it couldn't be done with a longer trailer as well, but not sure if it would haves one powered axle or two.

it looks like an EUROPEAN As trailer.
they use the front wheel instead of a post.
you can buy motors to move EURO trailers also.

maybe these is just for EURO and not NA

The development team is in Europe (ZF and Dethleffs). The first product showing was in Florida. No reason to show it in Florida if they are not planning a North American product. That said, I think it will have a strong European design influence. Hopefully it will be narrower for reduced aero drag. Another example: I don't know what the tongue weight target is, but it likely doesn't need to be 10% if they distribute the weight optimally, near the axles. That means it may not need WD equipment, which opens up the Euro market for the platform. Add in the electronic stability control, which could influence these factors further. The concept eStream doesn't require WD, but it is a concept. Larger trailers may differ. Not sure how the WD equipment would work with a load sensing coupler, but sense it is a non starter.

So many questions.

I think this is addresses the North American market. Thor did their show and tell in Florida.

I think there will be more platforms (Bigger trailers) available as this becomes a reality.

OK, now this part is very speculative.

The video clip shows the power management system. It shows the trailer is charging at 27 kW. The battery is at 38%. It shows a trailer range of 230 miles. And a time remaining to charge of 1 hour 12 minutes.

If those figures have any basis in reality, that suggests a range of 600 miles, or 545 miles with the battery at 90%. It would also depend on what the assist level is set to. And whether the rooftop solar is helping at all.

Elektrek likes it. They describe this as the RV industry's iPhone moment. And they are very amused by there being two EV motorhomes at the Tampa show. A Winnebago with 120 miles of range. Next to the Thor concept with 300 miles of range. Both built on the Ford Transit chassis.

The trailer looks nice. It looks like there is no rooftop A/C, no roof vents for air or plumbing. I know the images are CGI showing under belly but they showed no room for tanks. It will be interesting to see the real thing.

Interesting also is that the MH concept has a hydrogen fuel cell.

Greetings from the Florida Panhandle

I already have a Rivian R1T on order. I had already planned on using it to pull the Airstream on short trips. I am figuring that the range will be 150 miles on a charge.

This new Estream could really work well with an electric tow vehicle.

It is the future but it will not be cheap. The roof appears to be all solar panels. The cost of chassis along with batteries and drive axle will probably equal the cost of any current trailer of the same size today. Round numbers I would guess at least 2X the cost of a current trailer of the same size, maybe 3X. So question will be is there a market in that price range. I hope so.
