All of this is exactly my reasoning. Very well put, thanks for confirming, at least to me, that this may not be crazy after all haha.

Physical laws prescribe you cannot get something out of nothing, true. However, again, this is the hypothetical use case: You are going to a remote place. You need 2 work trucks. You need power source and it happens to be that your 2nd vehicle is a giant portable 100kW battery with a 7.2kW pro...

I heard once that real men/women drive cars with 3 pedals 😉

I forgot about that video! And in conjuction with what @Yellow Buddy said, I bet that if you have 2 vehicles going anyway and one is an HD diesel truck. It's gold. If a Tesla can do 1kW in 1km, I bet Lightning can do more, and a diesel HD truck can pull a lot more efficiently than a Raptor.

With 4 wheels on the ground, it pretty much just simulates going down an endless hill regenerating through and through. I wonder if doing the dolly with just the rear motor regen wouldn't freak the computer out. I guess there is no other way to find out besides trying.

Thank you for the theory and math, I was doing similar calculations haha. If a friend of a friend ever tries, in a remote location where it's safe ... for science ... I'll ask them for the numbers 🤫

Just to re-iterate, my initial use case was tow bar, driver inside the towed lightning, in remote locations without charging infrastructure. The safety concerns you brought up IF this was attempted without a driver are very valid. I also edited the initial thread to include the fact that to tow...

Thanks for sharing! Yes, the idea would likely be a tow bar, also very likely in remote/out of town situations and as little as possible. But the idea of not being reliant on charging infrastructure and that you could drive your Lightning for 700km by towing it for 100 is enticing.

I guess I did not take into consideration local law. I am in BC Canada, just trying to fish out whether it is illegal.

You are right. The only reason is that for my application/business case, I will need 2 trucks anyway, in a remote place where having a 100kw battery with Pro Power on board is a boon, but no chargers. While you are correct in terms of losses through powertrain, IF (big IF) I can pull the...

I think this is a great point. Considering I am intending to have 2 drivers anyway, might as well do 2 pedal. Both drivers need to be engaged anyway, this way the application of friction brakes would likely be minimized. Thanks!

Yes, it has caveats, however, my specific application would involve at least 2 drivers at all times anyway, so in those circumstances, eg. You have to drive 2 trucks for 800km and one is an EV, are you able to pull the EV for sections of the trip to avoid regular charging completely? Has anyone...

Absolutely. But without real world data, we are unsure. Example: saw a 3500 Ram pull 14000lb with 21l/100km economy. I don't think Lightning with a full regen puts out that much pull. In 100km, how much juice could you put back in? Empty ram did 13l so 8l difference, that's about $16 cad atm...

Is there, however, a mechanical reason it wouldn't be possible? If it's in the manual, I am sure you would void your warranty at that point. But in theory, putting it into one pedal drive and towing it should work for regen?

Hey everyone! I am planning a business that may require me to have 2 vehicles and one of them will be my 23 SR XLT. It will likely be remote places, so I wonder: Has anyone tried to tow your Lightning to charge it? I saw some videos and thought: if I have a HD diesel truck, it may even be...
