Better to tow with the front wheels on a dolly (if possible), I believe.
Except, you have to tow the extra weight of a dolly, pay for a dolly, and store a dolly.
Like I said above, you have to disconnect the front wheels from the gear box, and lock out hubs are a great solution. There hasn't been lock outs on four wheel drives for a long, long time (maybe heavy duty trucks), and I can't imagine a market big enough to attract a somebody to build a set for the LEAF. Plus, the front wheels would probably need to be changed or modified from the 66.1mm hub to something bigger.
The towing while in "READY" has been famously done, however the 20-30hp pull on a grossly inefficient motor home is a terrible waste of energy. I would do it, of course, if I needed the car charged at my next stop, but otherwise RV parks have plenty of places to plug in.
Having said all that, I would probably use a coupling at the half shafts where they enter the gear box, that can be switched on or off like the ARB air locker differential.
I'd put on a dash mounted switch. Now, I don't need a dolly, there are no miles being registered by the car while being pulled with the power off and half shafts disconnected. For those times I wanted to recharge the LEAF, I would leave the car In READY and ECO, with half shafts in normal mode.
Plus, now I have a standard tow bar on the front of the LEAF that could be used by any pickup or large SUV to pull the car if disabled on the side of the road. Always prepared.
