We rented a heavy duty ECV from Randy's last year. My husband is morbidly obese, and cannot walk for very long. The ECV was in excellent condition, almost new, handled very well, had a long battery charge, but it was REALLY heavy. DH and DS and I would fold it up and then do the heave ho and get it into the back of the Suburban. I know the smaller ones are not as heavy. Make sure you talk to the rental agency and ask them about portability and getting it in and out of your car. Many of the rental companies emailed us user manuals so that we could review before we made our choice on the model we wanted to rent. They were very helpful.
OOPS...you have already come and gone, haven't you...LOL....
