Least noise under power: Gas C or Gas A

[gfmucci]

I understand diesel pushers are quietest up front. But I wonder if there is any significant difference in cockpit noise level between a front gas A versus gas C?

And is there much difference in noise between various gas C's? I understand that the gearing of the tranny may make a difference accelerating or going up hill.

Brand dependent but generally I think a class C has less noise than a class A. Diesel Pusher quietest

A great deal of the noise level in any class A is the manufacturer and what he does to isolate & insulate it. Most class C RVs are pretty much stock for that part so are probably similar for coaches with the same chassis.

It really isn't true that a diesel pusher is quiet compared to a front gas engine, but the main difference pushers is the fact that the noise is back at the rear, but if someone attempts to spend any time in the bed while traveling, they will very quickly learn how much noise and heat insulation the coach manufacturer put into the rig.

With front engines, whether diesel or gas, a great deal is dependent upon the coach builder and it varies a great deal. In ours I improved the noise issue by adding more and better insulation to the doghouse. I think that most manufacturers have improved the sound isolation, but the best way to know is a test drive.

Thanks! Makes sense about class C because for most it appears that more of the engine is out in front of the cockpit rather than directly underneath or between the driver/passenger.

Here are a variety of sound deadening mat options on Amazon.

But if I wanted to start out with a quieter used (5 to 12 year old) class C, are there any makes that are better known for a quieter cockpit (better motor insulation) experience than others?

While you're considering the engine noise differences, also consider that Class A's typically can carry more "stuff" than similar sized Class C's, and have a bit more usable interior room than most C's. Since you'll typically be spending more time living in the RV than driving it, those items can be as, or more, important than the engine noise.

I have a C Class this a V 10 2009 made by Fleetwood 29 foot. my A class V10 2017 33 foot made by Georgetown. As far as noise when they hit a large hill they both make a great deal of racket. My service Dog may think there is a monster some were in coach her hearing doesn't like either one over the other LOL

Also adding products like Dynamat to the under side of the doghouse cover can make a big difference for either a gas class A or C

 

[grashley]

Ear Plugs will reduce noise from either

Gfmucci, well you have heard lots of opinions. Now you need to go drive both and do your own evaluation. I would drive A better quality gas coach like the Newmar Bay star. Gas Lineup | Newmar

On my gas Class A the doghouse design was inferior compared to a Class C with a factory Ford/Chevy van doghouse. The Class A coach builders know few people check out the doghouse before buying an RV. After it got some miles on it the engine smell was a bigger problem than the noise. I tried adding more weather stripping in places to seal it up but never succeeded.

After having owned both. I think my Class C was louder then my Class A.

Well, it appears I screwed up. And I can't revise it anymore.
Here is the one I intended...
Sound deadening pads

Those who have commented on this thread have roughly 1,000,000 times the number of hours of experience with MHs than I would accumulate test driving 20 rigs. That's why I trust opinions here more than I would trust a few of my test drives.

My current understanding is "better quality" could apply to both As or Cs to provide more effective insulation and have less noise up front. I'm now seeking which "C" makes and models in the +/-10 year old range are considered "better quality."

Newmar testing for me would be fun but irrelevant because even 15 year old ones are out of my league. But this does bring up a topic for another thread: Assuming a budget of $30,000, would lower maintenance cost be achieved with a 15-year old higher end model class C or a 10 year old middling class C, assuming size, drivetrain, and apparent condition when purchased were equal.
Or does "higher end" substantially mean "fancier with more amenities" rather than more robust?

I have started a new thread on the topic of price, quality, maintenance on 10 year old Cs.

Check out Lazy Daze if you can find one as they are at the top of the quality market, along with the Born Free, which is no longer built.
