I always keep my office windows closed (and on my vehicles too).

To make my experiment as scientific as possible (and not spend much money), I bought a $1 app for my iphone that measures sound levels.  I doubt it is accurate but it does give me relative differences.  The sound level in my office is about 47-48 dB.  The sound level in my f150 at 70 mph is 53-54 dB.  The sound level in my 2552 at 62-64 mph is 57-58 dB peaking at 60 dB.  Perceived loudness is doubled every 10 dB, so my f150 at 70 mph is about 50% louder than my office and my 2552 is twice as loud and my ears pretty much agree to what the meter is showing me.  I have to speak above my normal voice level for my wife to hear me when I am driving the PC and she is in the passenger seat.  The noise level becomes fatiguing after a while.  Much of the noise is wind on the cap, windscreen, and mirrors, but the engine contributes a lot too.  I'm very curious to see if insulating the doghouse with a premium insulation product will help.  There are several threads that say it helps, but it's all speculation about how much.

I sent Hushmat and Dynamat emails and asked them which product I should use inside the cowling.  They have both responded but I haven't had time to evaluate either product.  Hushmat recommended removing the existing insulation on the doghouse and chucking it (my words).  Dynamat also sells an exhaust wrap.  I found a thread on it and one user was very happy with it on his 450 van which I think is a diesel (Does Ford make a diesel 450?).  I also found a post where a user applied Dynamat to both the inside and outside base of the doghouse.  He was going to add carpet or some other flooring over it to protect the interior application.  He said he had extra Dynamat after covering the floor and doghouse and just wanted to use it up.

I'll be purchasing one of these products soon and will post up my results, but it may be a month or two b/f I'm done.

For anyone interested, I came across a craigslist ad for a "wide body" 2006 2551 with "fiberglass front and end caps" in Mobile AL.  Please delete if this violates the rules.  Mark

When I heard about this mat, I was anxious to get to my Ford dealer to order it.  However, looking at the pictures, I see this is what is already installed in my 2013 2552.  Interesting.   I may pull it up and see if I can add some insulation under it or put something else on top.

I pulled the cowling yesterday and there is a foil backed insulation product attached to the inside of the doghouse.  It looks like there is plenty of room to add more insulation except maybe near the exhaust.  I think this will be my first project.

I pulled mine off yesterday to see about adding some insulation.  It slides back easily enough.  Be careful about pulling on the cup holder for leverage.  The cup holder section is a drop in held by adhesive caulk.  On mine the adhesive didn't bond and I snapped one of the 2 seating tabs (that did bond) when I lifted the cowling and the holder popped off.  The view under the cowling shows you just how little separates you from the engine, transmission and pavement!

Thanks for posting this.  I'm taking my PC to the Ford dealer next week to investigate my vibration and I'm going to see if he can order this mat for me.  I'm also going to see about insulating the doghouse and see if I can make the inside a little quieter when running down the road. Mark

Our dogs were a primary driver in getting an RV.  We frequently travel on long weekends to dog trials with Winston and Griffin, our Glen of Imaal terrors (no misprint), to earthdog, agility, obedience, tracking, rally, and barnhunt events.  No, you probably have never heard of a Glen of Imaal terrier as they are the 157th least popular akc breed.  We like to say our dogs are better behaved than 99% of children we meet.  They are used to traveling and Winston generally rides shotgun.  He finds the captain chair is to his liking.  We don't crate them during travel based on the controversial thinking that if we are in a severe accident and they are ejected, being crated probably won't save them.  Mark

Bob commented that he thought the box by the propane tank was the HWH leveler system.  On my unit, I don't think that is right because it was all lit up with 5 or 6 leds and I didn't have the leveler system turned on.  I only noticed the lights on when I was running the generator and thought perhaps this was the transfer switch and the led's somehow indicate what the power source is.  Mark

I did a search on insulating the cab floor and doghouse and didn't find much.  Has anyone tried lining the doghouse with hushmat or a similar sound/heat insulation material?  It's pretty noisy in the cab area especially when the tranny downshifts at high rpms.  Thanks, Mark
56  Main Forum / General Discussion / Another sani con tank flushing question on: September 23, 2013, 06:24:20 pm
Thanks for advice here, I hosed down my black water tank with city water hooked up on the sani con panel.  After one rinse, the black water tank now reads empty instead of 1/3 full when it's empty.  Thank you.

On the sani con panel there is also a button for the coach water pump.  I assume if I open the rinse valve and hit this pump button, I'll flush the tanks with onboard water?  Thanks, Mark

I was told to hold the remote start/stop button in the stop position, light comes on, and then move the switch to the start position when the light goes out.  On the first attempts, it will start or try to start and after a few seconds, stop.  I'll tinker with priming it a little bit longer.  I hate to run the starter any longer than necessary.

I found the altitude adjustment and it is properly set at sea level.  I also accidently hit the start button on the genset when wiping up excess oil.  It was unexpected and scared the $%#& out of me!

The box on the other side of the propane tank is not the leveling system.  It was all lit up when the levelers were not activated.  These motorhomes have a lot of parts!  Mark

I have a vibration in my 2552 that I can feel and hear in the seat of my pants b/w 60 and 65 mph.  I had the tires balanced and it didn't help.  Today, I had a mechanic from the tire store (they do brakes, exhaust and other work) ride with me and he moved around the cabin as I drove.  He isolated the vibration to the front of the vehicle and he thinks it is a driveline issue.  The recommendation is to take it to my ford dealer and let him troubleshoot it.  I'll work on that next week.  He continued to say that if I can't get satisfaction from the ford dealer (hopefully under warranty), bring it back and they had a mechanic that would hookup sensors to the underbelly and he would monitor the vibration on a computer as it was driven.  If they can do it here in podunkville, they can do it where you live.  Maybe something to check out.  Mark

Tell me about the rubber mat they installed.  I think I could use one of those.  Mark

I changed the oil today in both the genset and the engine.  While checking for leaks, I noticed a box with a clear plastic panel facing forward beside the propane tank that had a row of 4 red led lights at the bottom  With the generator running, the first light was blinking and the rest were solid.  Is this the transfer switch for the shore power/genset?  What do the lights signify?  Why is the plastic panel facing forward where it is more likely to be struck and broken by stones?

I also noticed that my genset takes about 3 attempts before it fires up.  I hold the switch in the prime position until the light goes out and then rotate it to the start position.  Is this normal?  Once it starts, it runs fine.

Thanks, Mark
