I have seen this statement many times and all those saying that a CDL is not needed to drive a motor home need to rethink their position. There are 4 states that presently require a non-commercial MH to have a CDL licensed driver.
It is dependent on the requriements of those 4 states.
Here is a list of state requirements:

In many cases the state MAY require a special class license.
Georgia does not require a CDL or a special license.
