Are you talking about the show with Lee Van Cleef (of Western fame) and some punk kid in a van who travel around and do good deeds? They have a little hamster in the van in a cage.
Lee Van Cleef as John Peter McAlister, Timothy Van Patten, and Sho Kosugi.
I looked it up on IMDB. Yeah, loved that show....
The van was the coolest!
