What the others have said, is true. Trailers have not enough
wall thickness, and seldom enough insulation in the roof.
And leaky windows. And they lose heat under the floor.

What I've done in mine. A couple friends and I cut open the
ends of the roof, and blew in several bags of cellulose. I
had some 2 inch PVC left over from another job. That fit
into the blower hose, and allowed the guys to inject fluff
farther in. I'm sure the center didn't get insulated, but
it's better than it was.

A couple of the windows were single pane. I packed in pink
fiberglass, and then stapled plastic on the inside. Helps, a
lot. Looks awful. Who cares?

Under the trailer, I found some of the heat run,
uninsulated. That got packed with fiberglass, and then mylar
foil bubble wrap stapled up from under.

When it starts to snow, I fill the floor model humidifier,
and keep a little humidity in the trailer. During the bitter
cold, it takes about two galons a day of water. Which tells
me I'm losing a lot of air some how. I should go around and
do what I can to tighten up some more.

Also installed a 90 percent efficiency furnace, which helps
a bit with the fuel costs.

Here I sit, in my Mobile Mansion, feeling a chill in the air
and
wondering what I can do to make it better.

First I was thinking about 1 inch rigid foam over the
shingles with a
steel roof over that. Searching the net I see people are
filling the
entire "attic" spaces in mobiles with blown in fiberglass
insulation.
(Cellulose insulation is too heavy and can corrode steel
roofs) Well
mine isn't steel, it's trusses, underlayment, and shingles.
Anyone seen
something that looks good, or warn me about something bad?

I had one gable end open once so it looks feasable doing
blown in from
each end, but the drawback is the living room with cathedral
ceiling
leaves no access or room for insulation there. I suppose
that could get
the foam on the inside ceiling and drywall, but a second
layer of
drywall is probably too much of a load on it.

Any ideas?
