I don't know if others have said this, but the Leaf does not let you charge and drive....

It would be nice to be able to rent a hitch mount gasoline gen set for the occasional longer trip.

As has already been said here, it has been done, using a generator. It has also been done using auxiliary battery packs. And it's done by every LEAF via regenerative braking. It is not impossible and it is not a new idea.
I noticed you're still working with polymers.

My Tesla owning friend said I'd see posts like this on EV forums once I bought my EV.

What's the power source for this charging?

Indeed. I have a guess as to what the OP's thinking is. There are threads like that over on "TMC" that also occasionally pop up.

You're dealing with either a troll or a moron. Does it really matter which, at this point? Close the thread.
2013 "Brilliant Silver" SV with Premium Package and no QC, and 2009 Vectrix VX-1 with 18 Leaf cells.

The most offensive, tasteless phrase in use here is "Pulled the trigger." I no longer respond to posts that use it.

Yes. It is completely ridiculous to think someone would want to drive their car out of town for a trip once in a while. Something like a Prius Prime, Chevy Volt, or range extended i3 is a crazy idea. It would be even crazier if you could just leave the ICE/ gen engine on a trailer at the dealer 350 days/ year when you weren't using it so other people could use it.
.
Any short range commuter EV like the Leaf could be designed with a rear quick charge port option that would control a 20kW Gen trailer that, weighs 500 pounds, costs $3000, rents for $100/week and makes 40 mpgUS cross country.

There are wires on a 2011-12 LEAF behind the front seat that go from the rear charger to the pack. These same connections are less accessible but also exist at the front of 2013 + model years. Of course this requires expertise in HV systems and critical safety measures as pack voltages are lethal. Your charging source also needs to be safe, properly secured and isolated,etc, etc.

A more simple solution is to wait for a 200 mile range EV as it will cost less in the long run, be safer and avoid the many hindsight discussions with your friends you may wish to avoid. You can also contact one of the bankrupt companies that made range extended packs for the LEAF for some input.

My thoughts exactly on this. For most commuting, my Leaf cuts the mustard, I would only need a range extender on rare occasion, and a trailer would work perfectly for this. (Or maybe a hitch-mount setup.) If you knew how long you were going to be driving, it could even be a smaller generator, such as if you're using 20kW driving, but it generates only 10kW of power, it means you're only consuming 10kW total from the battery, thus doubling your range before you deplete the battery.

But all of this adds complexity that car manufacturers don't want to deal with, honestly. It's easier to just say it has X range and call it a day.
