That's a classic awesome set. I only ever had two technic sets. The first was the smaller version of what you have, so the only technic ability was steering. Then later I got a fork lift track that used air pneumatics to operate the lifting forks at the front.
Then I got annoyed as my mum chucked it all in the big box my other "normal" Lego was in, and I wanted to keep them separate.
However, I remember using those really long single stud red beams to build the chassis for an ECTO1 I built. They were often the base for my larger builds.
