I have always found that I get quite a lot of noise from the pop-top/carrier
on my '84 Westy at high speeds.     I drove just a plain Vanagon the other
day and apart from noise coming from the drivers and passengers small vent
windows, it seemed to be much quieter.

I have replaced the rubber with Bus Depot one but it doesnt seem to seal well
at all so I put some foam tape betweeen the rubber seal and the van roof, but
its still noisy.
Are there any tricks on reducing or eliminating wind noise from the carrier ?

thanks,

Steve Cotsford
