CL Sites

MJS90

We've been touring 3.5 years & todate have only used main sites. We'd like to try CLs but would want to have elctric hook-up, showers & tolets, washing up area,fresh water to fill up, toilet waste disposal. Are there any CL sites which have all these facilities?
The CLs we've seen appear to be very basic & have to rely on the facilities in the unit. Advice would be welcome.
