That episode of CHiPs originally aired the day after Rick's third appearance in Dukes (The Meeting).
Looking through his list of acting credits, I'd say that most have been in comedy/light entertainment roles, with several as police officers or soldiers. I remember him in 'Earth Girls Are Easy' and I watched his episode of 'M*A*S*H' a couple of weeks ago. I'd love to see him in 'On The Rocks' (the US remake of the British sitcom 'Porridge'), but a grainy trailer is all that seems to be available online.
It's interesting that his character in CHiPs was 'goofy'. The show sometimes dealt with serious subjects (armed robbery, drink driving, mental heath issues etc.), but there was often some light-hearted relief or even whole comedic episodes. It was a good mix.
