Copper air and fuel lines?

[Tim Hannink]

How long did Wanderlodge (and Bluebird?) use copper tubing for air
and fuel lines?

Is there a problem with the copper tubing cracking and becoming a
safety hazard?

I have someone trying to tell me that my 'lodge is unsafe because it
has these copper lines, he's telling me that most truck
manufacturers switched over to plastic lines in the early 80's
because of stress fractures in the copper lines. I think that he is
full of **it, as he has proven to be so in the past.

Any info would be helpful.

Thanks,
