Greetings RV People, I'm new here & seeking help. I've been told there are RVs that will hold & carry a small car. Can someone confirm this, and advise me which makes & models would do this? I would prefer a used RV. The car I'd wish to carry inside the RV is an 8'6" long Smart car; of course I know about towing the car behind the RV, but in this particular case that is not an option.
