This is true. The mouse fur and padded ceiling is a thermal break. No condensation occurs on these surfaces. BUT, the windows, vents, storage compartments, etc are still a concern. Many hidden areas which we don't see are also susceptible, like battery boxes, under sink and behind counters.
I still like the dehumidifier route. So far, I am really pleased with this one. Small and quiet. It's still new, so time will tell, but it stores pretty easily at only < 6" deep.

So far, I don't know. We've only had the trailer 3 weeks! Next outing we'll try the tips here mostly about leaving vents open a bit.
BTW, we owned property at SR for a couple years and wanted to build a house, but never could put all the right pieces together with jobs and things, so we sold the property. But it is one of my favorite places on earth. And if I recall, there is a LOT of moisture there.

I'm pretty sure the solution is pretty geographically dependent. I know, here in the midwest, when you get those cold spring and fall nights with rain/sleet/snow, humidity is high and interior moisture is WAY more than the cool humid outside air will handle.
You'll just have to see what works for you. I anticipate my dehumidifier will come in and out of the AS, depending when and where I am going.

Hey Redwoodguy, too bad the SR lot didn't work out- it's not easy to build with the seismic and septic regulations now. I'm an architect here so I know all too well the costs. I think it's absolutely true, the humidity cures are dependent on location and temperature. Good luck!

If what you say is true, my gas fired furnace in my house would keep my inside air nice and moist and I wouldn't have to run a HUMIDIFIER in my home most of the winter.

The natural gas flame of a furnace in a house in also in a sealed heat exchanger, and will not add moisture to the inside of the house. It will in fact raise the dry-bulb temperature of the inside air. The result is dry wood, dry nose, etc.

But, I have a question about condensation. Night time temps are about 35F here. In the am we have quite a bit of condensation on the windows. Our dealer told us the heat pump was the best way to get rid of the condensation. So, I have been running the HP for about 2 hours in the am after we take showers and what not. What do others do?
I hope this picture posts.

The answer to most condensation problems in Airstreams is ventilate, ventilate, ventilate. Use exhaust fans with a window(s) cracked open to let in the dryer outside air. If the outside air is cold, which it most likely will be, use your furnace or an electric heater to raise the dry-bulb temperature of the inside air. Neither will add moisture to the inside air.
The fan of the furnace will keep the inside air moving giving it less contact time on cold surfaces like windows and therefor will reduce the opportunity for condensation.
Remember those tiny fans in our parent's automobile that blew air across the inside of the windscreen - they used the same principle to reduce condensation.

I should have added to my reply to redwoodguy:
Using the furnace or an electric space heater to warm up the inside of the trailer will contribute to the possibility of condensation on cold surfaces like window glass. Considering the possibility of condensation; if its below 40F outside putting on a sweater is a better idea then using a heater (of any kind).

SRW - - Wow - - if it's lower than 40F I am going to need more than a sweater! Thanks for those comments. I understood them and will revise our practices.
I assume though that using the propane cooktop DOES add moisture - correct?

Damp rid makes several style of condensation products, I use the ones for our home toilets in the summer, they have standing ones for the counter and hanging ones for closets, I bet these would work great in the camper

Using the cooktop will add to the interior moisture in the trailer.
Electric space heaters do not add to the condensation because they are considered dry heat. The furnace will not add to the condensate since it pulls the combustion air from outside the trailer and it obviously exhausts to the outside.
Propane contains a certain amout of moisture. Since the cooktop and oven burners do not exhaust to the outside, they will contribute to the moisture inside the trailer.
Anything that breathes: ie humans, dogs, cats etc will expell moisture into the trailer, adding to the condensation problem.
Obviously items like tea kettles, coffee makers, showers, sink faucets will add to the moisture.

Only from a temperature differential standpoint. The furnace and electric neither add to nor remove humidity from the air. Stove does. catalytic heaters will.

Trailers leak. And dehumidifiers are great.
