It is very hard to tell what your asking based on the lack of information. However, if you're talking about the new/current Winnebago Vista series (27/29/35), then you would have a Ford F53 chassis.

Sorry, it is a winnebago vista with the ford chassis. Dynamat is a sound insulation material very popular for applying to the engine compartment.

I used the dyna-mat extreme under the entire cab carpet and doghouse,then 1/2" carpet pad over top of it,then new carpet,also did as much of firewall on inside as i could reach,including area under dash.The amount depends on how involved you want to get.Measure area,then buy accordingly.

Concur with the suggestion to do as much as you can, especially up the firewall and floor of passenger compartment. Just estimate what you need by measuring, add some extra, and then order some up. The foil-backed and approx 1/16 inch thick does wonders for the noise and also has some insulation value to minimize heat as well. You can also do the doors or side panels to help more. There really is no downside, the more the better.

I did the floor, firewall as far as I could reach, and the engine cover in my old super-C and it did make a nice improvement.

I used a similar product on my corvette coupe and it did wonders. I did the complete interior. It was a little about 16th inch. I was thinking of the 1/2 inch dynamat.

RICK. I am glad you posted this as I have been looking at the different products. I am pretty sure I am going with the dynamat as well, but have a small question? The extreme does not appear to have a heat rating were as the HOODLINER by dynamat is what is recommended for heat and sound. is there any issue with just using the dynamat extreme instead of the hoodliner product? Both come in sheets so application to the dog house would essentially be the same, both are about $160 for enough sheets to cover what I want and also apply some to the generator door and roof area. Just wondering.

There are many lower priced similar products than just the "dynamat" brand. Just search "sound deadening" on ebay or similar and you will find many options.

I have researched about everyone of them including what Fleetwood factory is using which is the spray on liner (Lizard Skin). The DynaMat is the only one that specifically has a heat and sound insulation factor in their HOODLINER product. I am concerned about anything under the doghouse with close proximity to the engine heat will degrade over time. The lizard skin is not as good for sound as you have to apply several layers to get the same quality of the DynaMat hoodliner. Lizard skin is probably easier to apply with the gun tho.

Dennis,
I installed it also on the underside of the doghouse,2 years ago or so,have had nothing fall off to date. I can not think of any reason why you could not use all hoodliner everywhere,95% of what I installed was inside,under the carpet.
