Tesla Motors New Model X.

The only caveat I see is that this. technology is very much in its infancy... In a few more years after the logistics of charging are buffed out, ev technology will be awesome, for now it's a very viable new technology, I for one can't wait to tow a big 15000 pound 34' Airstream with a long range traction motored tug!

My wife worked at a company that was doing electric city busses with battery packs about the size of a mattress. Makes me wonder if Tesla would team up w/AS to incorporate that under the bed of an AS so both trailer and TV can be charged while camping and extend the reach?

There's a germ of an idea in there somewhere I think 😃

Hey, one way to look at this is maybe battery technology will advance enough before too long where you can have an electric tow vehicle and just plug your Airstream into the electric vehicle overnight for power to the RV. It may even have enough juice to run your A/C!!! Now THAT would be impressive to RV owners.

Seems like an EV would be very boring to drive. I would at least need a recording of a V-8 Hemi coming through the radio speakers.

While batteries will no doubt continue to improve, it may be a long time before they make sense as a sole power source for long distance trips with heavy vehicles. That technology will be developed for trucks before it is developed for RVs, and could be based on a powered rail, a trolley wire, or some other system, along major highways. On board batteries would be used for local trips and manoeuvering, with grid power used for long distances.

But all that torque has it's own appeal......

Don't count on it. New Orleans has a relatively robust electric streetcar line, but guess what? Streetcars use about TWICE the energy of buses but have HALF the number of seats as a bus, so the cost per passenger is about 4 times as high for streetcars as it is for buses. The only reason New Orleans even has a streetcar line these days is due to tourism. Comparable cross-country electric-powered infrastructure would be far more expensive than highways, and only viable where the electricity is not provided by fossil fuels; New Orleans gets some— but not all— of its electricity from the Waterford 3 nuclear power plant.

Imagine the "social interactions" at the "charging stations"! Especially after a "natural disaster" like, say, an EMP!

So just for grins how about a Model X towing a modified Airstream.

By modified I mean the belly pan filled with enough battery power (be it GelCell or Li Ion or perhaps a fuel cell) to offset the weight , aero drag and the lost range due to towing that plugs into the model X to add to its power and give it a range of 250 miles when towing.

Ok I admit that this would be expensive . But there are a few other benefits to the modified Airstream , one could use that power for dry camping when towed with an ICE or as a back up power source at home . It could be scaled to any size trailer or power requirements . Of course one could also add Solar up top.

Oh sure this might be a long off nutty idea or like the cell phone of today seemed unlikely in the early 1980's but think of the possibilities .

In Vancouver we have no streetcar but many trolley busses. They work well and are cheaper to run than diesel busses, but are less flexible on routing. We don't use fossil fuels for power generation.

I think it is a given that as we move away from fossil fuels, that will include electrical power generation. Hydro, solar, wind, nuclear, maybe tidal.

Another comparison, and it uses heavily loaded vehicles, is off road mining trucks. 240 to 400 ton class. Some use diesel electric. On steep hills they pull under the power lane, and run on grid power. For loading and unloading phases, they move on diesel electric power. Not exactly the same, and it isn't common, but it illustrates the concept.

Explain, perhaps? HOV? You have a hovercraft? I'm sure there are a few on here that don't have a clue what you are talking about. I suspect a HOV is something that belongs in a large stinky unlivable city, not out in the open country with single lane roads. How do those EV things work on your basic unpaved open range roads with wild horses and cows and snow drifts?

HOV = High Occupancy Vehicles. A special lane just for ride-shares that lets you zip past the gridlock in the other lanes— assuming that you have enough people on board and can get through the gridlock from your on-ramp to even access the HOV lane on the far left-hand side.

HOV High Occupancy Vehicle lane in metro areas reserved for 2 or more people in vehicle during posted hours or motorcycles and certain alternate fuel powered vehicles with single drivers.

I ran into these last week in the Seattle area and another lane for tolls . Oh and metered onramps , i.e. a traffic light on the onramp . Oh the humanity !

Anybody know if you can tow with the current Tesla Model S? Seems like it would have plenty of torque and would be a good test bed to validate the efficacy and logistics of towing using an EV. It's a big car...
