No crazy rover (5)

I believe the answer is:

nomad

'rover' is the definition.
(nomad is a kind of rover)

'no crazy' is the wordplay.
'crazy' becomes 'mad' ('mad' can be a synonym of 'crazy').
'no'+'mad'='NOMAD'

(Other definitions for nomad that I've seen before include "Person always on the move" , "One travels from place to place with no permanent home" , "Member of a wandering pastoral community" , "Unsettled character" , "Damon (anag.)" .)

I've seen this clue in The Telegraph.
