Gas Class A road noise

[JonC]

While traveling in our 2021 Alante 31v the road noise is substantial. If we're on decent asphalt roadways it's pretty quiet, but concrete and deteriorating asphalt are really loud.
Doe's anyone know of an aftermarket system or Jayco upgrade that would reduce that noise?

There are close to a hundred threads on various forums about sound proofing the dog house and other areas around the drivers and passengers seats. Many use Dynamite and many use Fat Mat. When we had our Thor Challenger I used Dynamat couple with Dynamite hood insulation in the doghouse and I then used dynamite in the chassis area below the driver's and passenger's seats. There was a significant reduction in engine and road noise from the effort.

2 layers of Dynamat and one layer of Dynaliner in the doghouse and wheel wells. Big job but reduces both heat and noise. Reduced doghouse heat over 40 degrees (which improved Ford A/C too as the ducts did not have to flow through such hot air). Kilmat is a substitute for Dynamat and was easier to apply in some areas of the wheel well. Dynamat/Kilmat are for noise and Dynaliner is for heat, but both contribute to noise and heat reduction.
