Dogfood Dan And The Carmarthen Cowboy

I recently put this in my top sitcom list.

I remember seeing the series back in mid eighties I think it must have been and really enjoying it, but have not seen it since.
Is it available to watch anywhere or released on DVD?
I would love to see it again. All I can remember was that it was about two lorry drivers meeting in a service station and they both have secret lives. I seemed to think the guy who played Kirk from Dear John... was in it as the Carmarthen Cowboy, he was revising to be on mastermind?
Written by David Nobbs I believe.

Does anyone else remember it and even liked it? Or am I alone here? :)
