JAYCO Conquest 2018 25.3 Road Noise
Permalink  

Hi All,

We have a Jayco Conquest 2018, we have had it for over 1 year and enjoy it very much, however I was surprised with how much road noise came into the cabin when driving on those course road surfaces and the concrete roads in NSW. After a bit of investigation I found that there is a cavity in the transition shroud (between Fiat and Van) which goes all the way up the cabin, so recently I got two small cushions, took the covers off and pushed them up into said cavity, wow what a difference, I reckon it has reduced the road noise by over 50%.

Quieter travels.

Cheers

Using butyl & acoustic foam will improve thing a lot.

Hi Steel Dog

Do you have a picture to show what cavity you are talking about

I had vibration noise above my head, so I filled the roof cavity, with strips cut off an old foam mattress

Thanks for that, Steel Dog

My Fiat Ducato is the 2006 model, with the 244 chassis

The area you have pointed out, has no cavity on my model

The Jayco Conquest floor (which is insulated, and about 40 mm thick), is about 300 mm above the skirt of the body

I am not familiar with motor homes Steel Dog but it appears strange to me that there is a cavity in construction as you have indicated.

Maybe there is a panel missing which may provide some insulation.

If you havent already asked the manufacturer about this I would do so, or at the least, find another owner with the same vehicle and check if there is a panel missing.

Good luck with it

Regards

Rob

Opps, I have egg on my face, Steel Dog

Out of curiosity I have just had a real good look, (instead of a squizzy), at the area you pointed to
Yes I also have a cavity there

Without rubbishing Jayco (again), I can only surmise why that cavity is there

  • It was a marriage made in heaven, between Fiat and Jayco, and that is the holy bit
  • Due to the higher temperatures we are expecting, it is a Jayco built in, expansion hole
  • To entice the animal loving clientele, to buy a Jayco Conquest, it is there to help them smuggle their cane toads, over the borders

The picture says a thousand words
