Poster on here by the came of Camper_Bob has an EXCELLENT thread on Redhawk upgrades and the doghouse insulation job is one of them. Most def going to do the same job on my Grayhawk.

Well I finally got frustrated with air and dirt coming in from somewhere under the dash. Had taken this 27A Vision to the dealer and explained the issue and was told they fixed it after three weeks. They insulated the doghouse. Being that I did auto and truck repair for over 30 years I couldn’t deal with poor quality work and service, I removed the entire instrument cluster, radio, AC/Heat cluster and entire dash cap. What I found is the bulk head that is the front of the Ford chassis was not closed off and sealed to the coach. There was a two inch gap eight feet long between the front fiberglass cap and the metal bulkhead just covered with a pie of plastic corrugated 1/8 board held down by five sheet metal screws. Found four-five inch holes in side corners with no covering at all.
Remedy was to fit 1/4 coraboard to seal gap and seal all cracks with foam. Finally used Kilmat and covered entire area under dash cap and sealed all edges with metal tape.
What difference, not only in no more air blowing in while driving at exterior ambient temperature, the noise is cut by at-least 40%. Used to hear the engine suck air now the time it’s noticed is at a wide open throttle going up hill. Cost was less than a $150 but worth 10 times that. Sad that this wasn’t done at the factory as it took me two days to disassemble, repair and reasonable where as it would of taken twenty minutes on the assembly line.

Also it would seem to have silicone sealant securing it to the floor?

I would very much like to insulate the doghouse cover as it is putting off a lot of heat, not to mention noise.

How have others done this?

Attached is a picture of the cover.

In the other jumble of wires picture, I have pulled back the center console, only to find that the doghouse cover sure seems to run all the way back, with a let at the back.

Cheers,

There was a recall issued by Jaco for poor engine cover insulation that included specific serial numbers of Entegra coaches, including the 2020-2021 Visions. You can check to see if your serial number is included here: here.

Interesting. I was never contacted regarding this recall. My chassis VIN does not show as being part of this recall, but I think I will contact Jayco regarding this.

Thanks for the info, Lado!

would love some details on how the dash comes apart without disconnecting every wire and vent.
