*the answer for sound proofing Vanagons ???  ;o)*
**
*I've found that Chevy (GM) does it best. *
*Instead of making the interior cabin more quiet by adding insulation *
*and better door gaskets (spending the money and increasing the cost by a
bit), etc, *
*what do they do?*
* *
*They have this neat little device call speed compensated volume (SCV). *
*As you go faster the radio gets louder to help overcome the extra road
noise *
*and as you slow down the volume decreases.*

*I'm sorry dear what did you say?*
*I'm going too fast?*
*Gotta love those BeeGee's !!!*
