- jplante4Explorer III'm sure you'll be able to charge it with a $500 Harbor Freight genny.

I haven't seen any hard figures on the Tesla truck in terms of battery capacity and the like, but based on some quite rough back-of-the-envelope sorts of computations I think they would need somewhere in the vicinity of 1000 kWh for a 500 mile range in a semi truck (assuming normal highway speeds). Recharging 80% of that (800 kWh) in 40 minutes means that quick charger is supplying about 1.2 megawatts. Even doing it overnight is 100 kW, or about ten 50A RV sockets running at maximum continuous load put together.
(The basis for my estimate was a brake specific fuel consumption of a typical diesel semi truck engine of about 0.3 pounds per horsepower-hour and a typical gas mileage of 7 mpg and a bunch of conversion factors. As this is a very rough estimate, I may be way off, even assuming I did the math more or less properly.)
Widespread usage of electric RVs will require significant upgrades to the electrical infrastructure of campgrounds.
I don't know how much the campgrounds will have to be updated. Maybe a single megacharger in the high end camp grounds. But the RV portion will use the same amount of power as they do now. Most will want to recharge at a Megacharger. We rarely charge our EV toad in a campground. Once in a while a slow overnight trickle charge at 12 amps 120 but when you are talking about 300 to 400 KWH of battery unless you are there for a few days it wouldn't be worth it. Even a 50 amp site will only allow a charge rate of 10 KWH so like a day and a half to charge. I can see special areas with updated infrastructure being designated for this kind of thing. But commercial truck stops will get into the game as well. I think you
will see it overseas before you will here. Modern transportation is not a strong point of North America. A fast train here goes like 90 MPH. In europe 300 to 350 KMH is normal.
JMHO - John___AngelaExplorerWalmart just signed on for 5. Apparently Fred Myers ordered 3. People will approach it cautiously. Huge export market potential.

If it is an RV get your wallet out. Probably better off buying gas or diesel. also if it is a RV it will still will be built as cheap as possible, and with no quality workmanship or self pride in the workmanship. It's sad for what you pay for them.
Not necessarily so for the high end coaches and the reason why we always buy gently used. This way, we get the quality build and the price we demand. They're not perfect, by any means, but at least not bad.
Reason for the cheaper models that are built on a shoestring budget, is because John Q Public demands it and when newness is above all else. - ChainwrightExplorer

Same Negativity, Pessimism and narrow minded speculation as with the Prius and Nissan leaf when they first came out. But look at them now, 1/3 the market is hybrids and EVs. My mother in law is 95. She tells me about all the BS they were talking about the model T when it came out. Look at Ford now. I'm glad so many folks here got it all figured out. With that kind of pessimistic know it all we won't get anywhere. LOL.
Tesla's new Truck:
the specs are:
By itself. 0 - 60 mph in 5 secs
With 80.000 max load trailer 0 -60 in 20 seconds.
65 MPH full rated load at 5 percent grade
500 mile range rated load.
Charges 400 miles in 30 minutes.
1 million mile warranty.
Never needs brake pads.
Available 2019. There are two sizes.
battery pack specs for 400-500 mile range, rough capacity of 1,000 kWh
megachargers will be available adding 400 miles of range on the Tesla Semi in just 30 minutes.
Experts are speculating on a price tag of around $250,000 (slap a cabin on it for $150k and $50k to put the Newmar or Fleetwood or Winnebago name on it and you got a coach for $450K. And if you think $250 is to cheap well hey double it and make it $500K then $200k in additions plus the name, now you got a MH for 750K, still less then a King Aire, Prevost or Newell, just to name a few.) - ChainwrightExplorerSame Negativity, Pessimism and narrow minded speculation as with the Prius and Nissan leaf when they first came out.

- wildmanbakerExplorerWell, he can claim anything he wants, but lets see it happen. 500 miles for an OTR truck, yea, that's going to work. What speed are they talking about? No mention of the cost yet. It will come out at the same time the charging stations are in place. As mention, it will take a large amount of power to charge the batteries. Just what will be the cost of recharging, the same of operating a diesel? Great publicity, but lets see what actually develops.

I'm sure that it won't happen in what is left of my life but who knows down the road. - jplante4Explorer II

That would be cool as long as they're not built by Hindenburg.
