I’m sure it would. It would be like driving with your brakes on for half an hour, and of course that would affect the mileage of your Motorhome. There is no free lunch.

It would be convenient though. Arrive with a charged battery etc. We’ll have to wait to see what Rivian comes up with.

I have played with this idea for a while. (Play; no MH, no EV, no knowledge)
I'm sure the regen would be a drag. But could it be controlled? Say on with the Jake? The one issue I see would be the Batt at 100% charge, the braking is gone. But then dream a little more. At some level of throttle opening, could the motor engage? Reprogram the cruse control so hold the vehicle in place behind MH on it's power? That would reduce load on MH powerplant. Or even push the MH to the point of tire slip. This would allow a smaller engine to climb hill or accelerate faster.
I think it would be a fun discussion

Yes, but another inexplicable “no big deal” oversight by those blinded by Elon’s luster.....

ROFLMAO!
And this, folks, is the world some problem actually live in....sweet dreams!

I’m not even going to look it up,but regenerative charging provides only a small fraction of typical charging. It can’t do more than that until those Unicorn Farts actually become real!

The software on the car would limit the regen braking as it got closer to 100 percent battery. That’s why most EV’ers on a day to day basis tend to only charge to 90 percent so we don’t lose regeneration. We charge to 100 percent before toad trips and of course driving style has to be a little different until you wear off 5 or 10 percent. Not a big deal, but part of the discussion for sure.

The EV would control the regenerative braking based on speed, same as when driving. Would not have a provision to coordinate with the MH brakes. Eventually the battery would fill and the regeneration would be reduced to zero to protect the battery. As said virtually no EV is rated to be pulled four down.

Yes if the EV could be towed four down and coordinate braking with the MH it would be a wonderful system. Could potentially fill the battery from just stopping or controlling speed down a hill.

Elon, are you reading this?

Grit Dog,

Please read the thread. Regen is dependent on speed and may be quite high.

As to vehicles, my current choice would still be the Kona. It has the range I need. Now if the price would drop.

time2roll apparently Rivian can be towed 4 down.


Regards, Don
My ride is a 28 foot Class C, 256 watts solar, soon to have SiO2 batteries, 3000 watt Magnum hybrid inverter, Sola Basic Autoformer, Microair Easy Start.

Do people just go crazy at an RV park?
Apparently so. Having owned parks for going on 20 years, not having parking at the site for personal vehicles is a huge issue. I would never, ever reconfigure or build a site where the occupant had to park anywhere but on the site itself. Maybe it is because they usually have a lot of personal items in that car related to vacation travel. Things like expensive cameras, spotting scopes, expensive fishing gear, climbing equipment etc. Or maybe they just don't feel comfortable having their personal car out of sight. But it would be a big customer service negative in my opinion if the charging had to be done at a location away from their RVs.

Good to know. So adding a pay to play J1772 EVSE on a half dozen sites would probably suffice. Get the 24 foot cord version. My guess is customers towing with an EV truck would pay through the nose for the convenience of “fueling up” right on site. Or just add a second 50 amp plug with a padlock and charge a flat rate for access. Maybe 50 bucks a day to use it. Maybe more.

In Norway, they use twice the amount of electricity per capital than the US because of the EV charging. Just where would we get this electricity? In Germany they have had to resort back to fossil fuels because all of the solar is covered in ice and snow. Can EV, possibly. Is it the cure all, not likely.
