I think there are few, but one who comes to mind is Darrem.
Saw the Road to the O last year and his interview with Chick (nice job
by the way Chick - but can you fix the lighting?
).
Humble guy, well spoken. He doesn't appear to let success get to his head.
Yes he has cars and a nice house, but he also has a beautiful wife who he's been
with for like 20 years (who even in her 40's still competes in shows) and a son
who looks up to him and wants to be like his daddy. Seeing them train together
is like seeing best friends rather than father & son. How many parents out there
have such a relationship with their teenage kids, where there kids still think dad is cool?
He seems to have family life down, with a career already well in motion
after he stops competing.
He maintains a desireable physique and while he admits to taking drugs later
in his career, he doesn't abuse them and doesn't try to play the size game too much.
