We have visited Memphis on 3 occasions in the last 9 years, usually in January or March, and love the city for it's music and attractions.
We have traditionally stayed at Graceland RV Park and found it a good park, safe, secure and reasonably priced.
We have heard from local residents that even the Beal St tourist area has certain nights that as a tourist you really do not want to be there for safety reasons.
On travel days we will stay at the free locations, but we would not consider a free overnighter at Cracker Barrel, Walmart or Flying J in the Memphis area.
Sometimes it is just not worth the risk.
I have also read where the Tom Sawyer RV Park can flood at certain times of the year so be cautious.
