Thanks for the input so far. Hoping to hear from owners of more recent models in case something has changed.
To clarify, my goal is to tow the LEAF behind a 24' motorhome, which has a 7500 lb tow capacity as well as about 7000 lbs difference between GVW and GCVW. So it has the capacity. We would then use the LEAF for day trips from the campsite, and charge it overnight at the campsite.
I had looked at renting a drive-on trailer rather than a dolly - the prices are $55 & $45 per day respectively so that's not a huge difference, but that will increase the total vehicle length for the campsite. Also ultimately I would hopefully purchase rather than rent, and storing a dolly in the same parking space where we park the motorhome is doable, whereas storing a full size trailer is probably not. But I agree dealing with a trailer is less hassle than dealing with a dolly.
What I really need is an electric street-legal ORV with a small trailer to pull it on, but that's probably a discussion for another time/place
