So I learn. It would take some reprogramming to tell the toad to roll with no foot on the go pedal. And some to have the first part of the proportional brake controller to regen, then when more brake would start the friction.
Not that's getting into territory that will never happen.
There's no way to get a toad to receive communication from MH, much less be able to communicate back to the MH.
I'm talking just about the toad being set to charge at some unknown charging rate.
Both our EV’s have neutral positions on the selector. You can select it on the fly and the car literally free wheels. However. The cars need to be on.

The old-style truck manufacturers have tow packages. It's not beyond the realm of possibilities that an E-truck could have a toad package.

Regen braking is exactly that. No throttle, regen applies to load to match coast down FMVSS requirements. Apply the brake, and they system applies greater regen loads... until you exceed regen loads and friction braking takes over.

I would expect the easy thing to do would be to run your generator and have an output to the EV to charge while towing.

Yah. Really it’s a matter of software and a brake pedal sensor for the Motorhome. Just a matter of someone writing it and the warranty thing.
In normal driving of the EV, you want to slow, step on the brake, does the regen start then? And can you lift your foot from the go and whoa pedals, coast for some distance? (Remember, I know I'm ignorant.)
And most brake systems use some system to move brake pedal of toad? Any brake systems that do not use input from the MH brake pedal?
Unless I'm way off on any of this, I would say it would take very little change in programming, the technology is there.
Now I can see it would take some re-programming, but not a lot of change, for the toad to help the MH. And likely some changes to MH. (At least something to let the car know it is behind it's MH so it would not try to ride that close to another vehicle.

I guess I'm not explaining myself properly or my idea is just too stupid. The bus is dragging the toad down the road; the toad's wheels are turning; the toad's motor(s) are turning - throw in a little regenerative braking on the toad and its battery will charge. The bus has to work a bit harder but there is no modification to the bus.

We got a little off-topic here, but I've learned a lot... appears charging EV while being towed isn't a sensible option... thus, if one anticipates a lot of use while situated at chosen location, best to use ICE vehicle. EV charging while on the road appears less reliable...
