Looking for a movie made in either the 80s or 90s about an older woman who lives in Canada. Her husband dies so her son brings her to the US to live in his basement. Mom doesn't like the basement to takes her money and flies to Australia to see her daughter. Her daughter doesn't want her around, but a grand daughter likes her and loans her boyfriends car to grandma. Grandma runs away and heads out on a road trip across Australia. She meets up with a grumpy old man and ends up having a running battle with him as they both take their vehicles (his is a ratty motor home) across country. They, of course, eventually fall in love. At the end of the movie the woman has regained her self respect and is in control of her own destiny again.

What is the name of the move, what is the name of the main actress, the man she fell in love with? Where can I buy the movie?
