Wintering in a purpose built coach

[chessie4905]

most of that black is years of diesel soot and fumes  just because tailpipe is at rear, it still gets althrough the body. First discovered this in the Olds diesels, of which I had a few. After a lot of miles, you could see it around the fabric. Back then, not  much of a concern. You could really see it on school busses. Someone cracks an orange in last seat, you could immediately smell it upfront in drivers seat. Werent allowed to eat on the bus back then.

by far the best thing I did with my 1990 M C I was framing out all the metal frame work with 3/8" ply and framing down the ceiling for more insulation and  having the shell spray foamed at the start of the build . and yes there was little to no insulation in there from M C I

another benefit is how much quieter and solid feeling it makes the coach.

I'm not sure that's true of the '96. It seems to have insulation. There's 3" of fiberglass in the escape hatches for instance. Why would they bother if they didn't also insulate the roof?

there was only about 1 1/2" of crappy fiber glass in the shell , sides , roof with more in the floor but not much . as the only time the bus was used in service was when the engine was running with the heat or a/c on . not good for dry camping

That's all the S&S's have.

maybe the shitty low end ones but not the high end built for a customer to the way they wanted it

The '94 MCI we're taking apart had all the voids in the roof packed with fiberglass, even inside the beams.  The walls are filled with preformed tight fitting foam panels.  It seems pretty decent for a vehicle.  (Also water leaked in apparently at the end of the rain gutters and rusted through the side panels and a tiny bit of the wall frame, so that is probably a place for you to reseal. I can send pictures of the damage if you're interested.)

I replaced the roof on a cheap travel trailer.  It had about 1" of fiberglass sparsely applied.  I filled the voids with fiberglass, except for one where a fan could have been mounted.  That spot was hot to the touch with the sun shining down, but the rest of the ceiling was not, so fiberglass is definitely useful.

We spent a month in my 1981 MCI this summer.  It feels like it doesn't have much roof insulation.  I really wish it were more insulated but there is no way I'm tearing everything up to redo the insulation in the roof.  If I ever buy another coach I will look for one that is partially done that I can insulate and finish or one that has been completed with good insulation from the beginning.

Don't you just love it when a plan comes together. Sounds like pooping in tall clover!

Dan thanks for confirming my idea on the check valves the Aqua Hot hasn't missed a beat since I remounted those
