Can Someone ID This Video?

This is just one of things that’ll bug me. I was watching a video for a rock song, most likely a 1970’s tune later supplemented with a video once MTV came along. The scene is a van or VW bus running down a steep, grassy hill. It is almost like the mototcycles running down hill in"In A Big Country" video. Anyone think they know what video I was watching? 90% sure it is a 1970’s tune.
