Sound deadening material - details

Well, my contact at Allison retired, as did her husband who was with GM. I asked Allison to forward my email to her home, which they were kind enough to do.

Link to the material noted in the last email.

Thanks Don,

I am familiar with the Dynamat line of products. They make sound
deadening and heat insulation material that comes in a number of forms.
The racing and custom car communities are frequent users of it and
other comparable products. I was just wondering if anyone out there had
actually applied any of the stuff to their Kodiaks.

Some examples of applications I'm familiar with:

1) Lining the doghouse cover as you indicated.

2) They make a hood liner kit that conforms and adheres to the inside of
the hood and works to deaden sound as well as heat.

3) The Dynamat material is frequently applied behind the door panels
where it's adhered to the inner metal surfaqce of the door.

4) Also applied to floorboards, firewalls and behind the headliner.

Dynamat products typically come in sheets of flexible material but they
also have some spray-on products.

Unfortunately the stuff isn't cheap but I'd like to try it out one of
these days. I've got an old Radio Shack db meter and I plan to take some
before and after readings as the stuff is applied to different areas of
the truck. This is sorta high on one of my to-do lists but is
considerably lower on DW's "will-do" list so who knows...

Bill, when you blinked we elected you official tester and researcher of Dynamat. When it gets to the top of the job jar let us know please.

Well that title should definitely impress DW... Ha!

Incidentally we are on our return back home to No. GA. Had a good month+
visit in Central Fla but now it's back to reality and much colder
weather.

The Kodiak performed flawlessly and was a pleasure to drive the entire
trip. Even without any chassis upgrades it was a comfortable drive. The
upgrades would have made things more comfortable with tighter control
but all-in-all very acceptable.

For the most part the Jayco part of the rig performed well too. We are
very pleased with the layout of the 33DS floorplan. It suits our
lifestyle well. No major complaints other than that it sure is a
cold-blooded rig. The temp outside is in the 30's and I'm sitting at the
table now with the furnace blasting... the upper part of my body is nice
and toasty warm but the my legs and feet are cold due to the chill
rolling off of the windows and from the rigs various cracks and
crevices.

I feel your pain. A couple of things that have really helped us as we had a visit to the Tahoe area to visit my daughter - who is working AmeriCorps there. 

Ceramic Heater: I got to tell you this Lasko Ceramic heater performed beyond my wildest expectation. It kept Roscoe Ventura toasty with little current draw and we hardly needed the furnace. (Amazing as it was in the teens) It has a high (12 amp) and low (8 amp) settings. At 5000 BTUs it is way below the heating power of the furnace, but it does the trick and saves LPG. Lots of safety features including timer, temperature setting, overheat shut off... We use model number 6410 which looks good as well.

The only downside is that the furnace ducts were designed to have some of the ducts run close to the water system to prevent freezing, so below a certain temp it is a good idea to run the furnace if your Jayco is this way too. We also keep one of those hanging safety lamps with a low wattage bulb in the pump house to keep any pipes from bursting, disconnect the water hose nightly, and use lots of RV antifreeze!

Roof Vent Pillows: They work for both hot and cold. You just push them into the vent and voilà.          

I think I spotted these at CampingWorld after a recommendation from a 5th wheeler I trust.

For a more complete list of suggestions you can peruse "how to cold weather camp."

I did load up at HomeDepot with foam self adhesive weatherstrip and foam pipe covers, that and a little duct tape can go a long way towards comfort. Oh and we have an AdCo cover for the windshield (mounts on the outside - a vinyl cover - with magnets, and you really want to shut a bit in the door and hold it down with the wipers (for wind) - then add the curtains and you can keep the cab from bringing the temp down.

Good luck.

Bill, I wish Jayco had made heat pumps optional - we would not have hesitated to get such an option. We had them on our last two MHs and found them very good heat. I'm not sure the Journey had defrosters in the heat pump (central) as they said it could not be used below about 35 to 40 degrees. The Ambassador had two roof top HPs and they worked well even at 30 degrees and even lower.

I have to say I don't like the propane furnace and we use two ceramic heaters instead.

-We use a edenpure and the smaller one is fabulous. It heats the
entire Seneca with no issue and does not take oxygen or moisture out
of the air for under 250. We had two ceramic heaters and we love
this edenpure. In fact we have two in our home and never turn the
furnace on with 2k sq feet. Wonderful. Dane

Kevin,

Thanks for the comprehensive response! I especially liked the "how to
camp in cold weather" link... it's a great reference with lots of good
ideas all consolidated in one place.

Some of these things I've already done and it's helped. None of the
plumbing is enclosed beneath our rig... all of the water lines, tanks
and dump lines/valves are exposed to the elements underneath. The
holding tanks do have heating pads though. I also loaded up on foam pipe
insulation from Home Depot and spent the better part of a day crawling
around underneath covering every pipe I could find.

Probably the best thing we added to keep things reasonably warm and
comfortable was to make a curtain/blanket with the "Warm Windows"
insulation material to hang between the cab and the living area. It made
a dramatic difference.
