Insulating the doghouse

I did a search on insulating the cab floor and doghouse and didn't find much.  Has anyone tried lining the doghouse with hushmat or a similar sound/heat insulation material?  It's pretty noisy in the cab area especially when the tranny downshifts at high rpms.  Thanks, Mark

Hi Mark,

This reply doesn't answer your question directly because I've not considered insulating the doghouse before. 

But, I agree that the engine noise is very loud when the tranny shifts down at high rpms.  This happens to us when the engine is trying to maintain the speed I have set (usually 55mph or less while we're towing here in California) on steep climbs.  I've found that if I just release the speed control and ease off on the gas pedal a little the tranny shifts back up and I can maintain 45mph at the lower rpms with less noise.

We're usually not in a rush to get somewhere, so that works for us.

Please let us know if you find a better solution for yourself.
