We live in a seven building garden we are in Building #2 on the 31st floor. But we have a big parking lot in the front of the building also underground parking for rigs less that 2 meter height.
Since it's just a parking lot you'll be responsible for finding a public restroom to dump if you have a cassette toilet, I've never seen nor heard of an RV in China with a black water system, as there is no infrastructure for them. Other than that just as in any public area keep clean and all.
In the City of Shenzhen, China, Nanshan district, Shekou township all at least 4 lane access.
It's the parking lot in front of our building
More info on these via internet: Sea World (but not like USA this is more of a culinary destination), Window of the World (recreation spot with night shows). Shenzhen Bay Greenway (50 km of bike and walk trails with many parks). Many bars and resturants within walking distance, also 5 minute access to Metro Subway, and bus stop on East side of the lot.
