Reasonably decent towed vehicles for a Class A

I own a Tesla and would like to take it with us on the trips we take. But you can't flat tow so it has to be on a trailer. That makes taking it along a problem as a trailer has to be purchased. Then not all rv parks are set up for ease of parking the motorhome and trailer. I do see many trailers behind MH's but it just isn't something we are wanting to do at this time. Flat towing the car we do take is Sooo easy.
