Has anyone considered painting the inside of the outer skin with roof sealant before insulating to stop the skin from "sweating"?
This seems like it should work as the areas where the original bus manufacturer put the black adhesive to stick the fiberglass insulation doesn't sweat but the clean areas around them do.
BTW I'm using 1 1/2 inch of styrofoam sheeting for insulation. |

Sweating comes from poor ventilation , or poor choice of heating units.
An unvented propane heater(death trap) or Kerosene unit will dump 1.2 to 1.6 gal of water into the air (depending on whose calculating), for EACH gal of fuel consumed.
The drier needs an outside exhaust, the fridge needs the factory vent system.
An exhaust fan over the range , an exhaust fan when showering may help solve the problem.
RV in 12V would be best.
Air to air heat exchangers would not be needed as coaches are not anywhere as tight as a new home.

I'm with Fred on this. No "vapor barrier" or insulation will stop condensation. You gotta ventilate.
Two roof vent/fans minimize condensation in our 35' coach in all weather conditions. One in the galley/dining area, one in the bath/shower. With Maxxair covers, they can be kept cracked open all the time and are except when underway. When showering or cooking, the appropriate fan is set on exhaust.
They also do a good job of ventilating the bus in warm weather. |

If the only control is ventilation then you have to determine what humidity level you need for good health and then the dew point will determine what is the minimum outside temperature where you can take your bus. |

NOT SO
Any proper furnace or heating device that is vented outside will never have any condensation problem.Warm air holds more moisture than cold air.
AS it is the nature of Air Cond to REMOVE moisture , there are no condensation problems from cooling the air , particularly if the air is recirculated.
Ventilation CAN controll excess moisture dumped into the coach from showering , cooking , or having 25 folks for dinner.

Fred. I understand your point, but I was referring only to heating. When the outside temperature is low, condensation takes place on interior windows when the humidity is above 20%. This is much to low for healthy lungs and skin. If you live in a cold dry climate you have to use humidifiers in a house to keep the air healthy. You just have to control the humidity level at minimum condensation on windows. |

Hmmm, 20% humidity is much too low for healthy lungs and skin?
Can't be too unhealthy, Las Vegas in the Mohave desert, has been one of the fastest growing cities(if not THE fastest growing city) in the world for a number of years.
Seems to me, that I can remember days here in Las Vegas 20 years ago where the humidity didn't top 2 or 3%... of course, that was before we added a million people.
So, I checked a weather website and discovered that on June 15 2002, the humidity reached a low of 4% and averaged 10% for the day and it was much the same the following day.
Humans thrive while living in single digit humidity, I think that goes for living in a dehumidified coach too.

Well, Fred folks suffer Las Vegas for a lot of reasons...
Besides having no state income taxes, and more construction and service related jobs than any place in the country...
Other reasons to suffer Las Vegas: 95% sunshine, with an average year round high temp of 85 degrees, an average low of 56 degrees and an average yearly rainfall of less than 5 inches...
Plus, 6 months of summer, 3 months of fall, and no winter in exchange for 3 months of heat.
Not to mention the natural and man made wonders wihin easy driving distance, including: The Grand Canyon, Death Valley, Zion Canyon, Seqouia National Park, Hoover Dam, Bryce Canyon,Lake Powell, The Valley Of Fire, Red Rock Canyon, Lake Mead National Recreation Area, etc...PLUS Los Angles, San Diego and Phoenix within range of a day trip.
All that, AND the obvious attractions.

Brian said "Plus, 6 months of summer, 3 months of fall, and no winter in exchange for 3 months of heat. "
I grew up in Florida and I have to say that the 3 months of summer with scorching heat (comparable to St Louis) is just as bad as a cold winter in my book - the results are much the same - inside the house most of the time. In St Louis, it is the 3 months of winter. Either way the result is pretty much the same.
I guess the only solution is to ahve a house with wheels under it.

Well Doug, the BIG difference between the heat of Florida and Las Vegas IS the humidity!
A while back a friend of mine and I played 18 holes of golf at mid-day in July, it was 114 degrees and it was great!
I shot an 81, and we both enjoyed it so much we did it again the next weekend... When I shot an 84!
While I truly feel you can get a lot more accomplished in the heat of a desert summer... as opposed to a frigid snow covered winterscape... I have to say that 9 months of EXCELLENT weather more than makes up for the three months of bearable heat.
PLUS, the lack of humidity, and rainfall, means that your large posessions don't simply rot away before your eyes, outdoors.
Having been born, raised, lived and survived through 21 years in the frozen wastes of New England winters, I can safely say that I will never live in that type of climate again.
But... I do agree that having yourself a rolling home on wheels that can allow you to go from one good season to another, from a summery Las Vegas spring, to a lovely New England summer, is, to coin a phrase, the best of all worlds.

Yep, and the castle gate knocked my ball into the moat Doggie, but it was 18 holes not 9.

Brian - I don't disagree - I was pointing out that most every climate has time when you don't want to spend much time outside. July in Phoenix (at 115 deg) feels like Florida at (90 + humidity) to me. Not fun. On the other hand, New England is not a comparison to St Louis weather-wise. Maybe you prefer 115 degrees! Great!
Oh well, to each our own.
