With my Dometic it ony has one temp contoller, so how could I run the heat and AC at the same time? I could run a small electric heater and the AC, but if the temp gets below 32 I need the furnace to keep the tanks from freezing, and How can I run the funace and the AC?

You run the AC and the furnace. Both have separate thermostats.

Andy.....there is something just wrong
about running the AC and Furnace at
the same time. Perhaps, maybe, for a
very brief time. Surely not as an ongoing
solution.

You run them just long enough to get ride of the excess moisture.

Andy-
Ok and usable as a short fix.

I posted this in the other thread aslo:

Open a roof vent(s) about 1/8 of an inch
to let the moisture out - heat rising will
carry the moisture out - dry heat from the
floor level will rise.

One more thought - wall condensation
and ambient humidity....though they are
related - they are also different items.

In a damp climate (like Maryland) there's something to be said for a dehumidifier. You can get a fairly small marine dehumidifier that runs on 110v and does a decent job of keeping an interior more dry than the exterior.

why not dehumidify between trips

We've used the air warming units 2air mentions for years in a crawl space in our house. Purchased inexpensively through a home improvement catalouge (can't remember which). Seems like a practical idea to use between trips whenever the AS is empty as well. Much cheaper and easier then a dehumidifier. But if so simple and easy why don't more folks seem to use the? Is there another issue?

A number of companies sell air purifiers that supposedly limit mold and other growth. Anyone try leaving one on when the AS is empty to prevent stuff from growing?

Our new AS has two holes in the board underr the bed, one to the outside storage compartment and another ....well i have to look. I presume that these are to provide air circulation under the mattress, but how can they really circulate any air with a mattress on top covering them? Would seem that some type of frame under the matters to permit better air flow is essentional. Is this commonly done? Using what?

Thanks.

In Maryland, I don't think I want to make things any warmer inside the coach... at least not for three seasons out of four. Here, the problem is heat and humidity.

Without doubt, good air circulation can help... but it's important to note that we have our share of very humid days. Moving around moist air is not the same as actually pulling moisture out.

I think a small marine dehumidifier would work wonders. The only issue is finding a location for the drain. If I can find a small unit, I'd like to plumb it into my gray tanks. The dehumidifer in my basement can be programming to run in cycles or to a particular level of humidity to save money on power.

I'm not opposed to Andy's suggestion, but in wet climates, I think a dehumidifier is a good investment.
