Doghouse insulation -- question and discovery

Today I removed the doghouse in my class C in order to install some insulation in hopes of reducing engine noise and heat coming up thru the cab floor.

I used a product that looks like Reflectix with a closed cell foam center rather than bubble wrap. The question I have is this. Is it important glue the insulation to the inside of the doghouse? I don't see anything under the cover that moves.

Now as to the discovery -- my RV's doghouse has cup holders and small storage spaces on the front edge. I discovered today that that is a large removable piece. I'm amazed how much easier it is to climb into the driver's seat, but I'm not sure how much I'll miss the cup holders. But I can always snap it back on.

This is what I used to sound proof and insulate our dog house and it has worked great and easy to install. It's a heavy, thick material and self adhesive. You will cut this material into several pieces to—"form and fit"—the entire area, and then use either a wooden or metal hand roller to "roll & press" into place to insure a good adhesion. Took me about an hour to do my dog house.

I redid the sound and heat insulation on our Georgie Boy doghouse. It was a carpeted fiberglass cover. I had to take the carpet off, then I used Duramat sound insulation over the cover, then reglued the carpet on top. I used the Duramat silver reflective heat insulation on the underside. The sound insulation is heavy, and the adhesive would not have held it in place if I had put it on the underside of the cover. Much improvement.

To piggy back on this thread I need to replace the insulation on my dog house, but I also need to replace the seal. Anyone have any luck finding replacements? Mine is a 1977 Chevy. I even have the actual complete 1974-1978 GM light and medium duty truck parts manuals and can't find anything conclusive in it for a replacement.

I removed my seal while cleaning so I got a good look at it. It is made by joining the ends of a material that might be sold by the foot. You might be able to find one at a junk yard or RV salvage yard off a newer vehicle with the same size motor. If you are anywhere near recent flooding there might be several to choose from.

That may possibly work. I have to look closely at what the dog house has on it. Chevy changed the doghouse in 1978, so if it fits an 80's-90's unit, it may not fit a 1977. And then again it may...best I can tell GM calls for a different part number for 71-77 and 78 on.

I suspect both use the same type of gasket material, but are different sizes. Measure the perimeter of your doghouse and find one that size or larger. This might be a place where new material is best. I'd be afraid of leaks around any gaskets over 10 years old.

Try LMC truck. They have restoration parts and I believe you could buildawhole truck from parts

Many years ago I remember hearing that if you bought a car one part at a time it would cost you 4-5 times as much as a buying that car new from the dealer

Reminds me of the early M*A*S*H episode where Radar was sending a Jeep back home one part at a time.

I got an LMC van catalog. Nothing satisfying that I found there.
