[VAC] 40's Pipe Frame models

[Charcigar <stogie@xxxxxxx>]

Hi Everyone,

 

 Can anyone educate me on what a "pipe frame" model is all about?I understand that the 40's and early 50's were built on a "pipe frame".What exactly does that mean?Are they then weaker structurally than say,later 50's and 60's Airstreams?

 

 Thanks!
