Question,Condensation (yes again).please bare with me.

Hey guys,
I know this is a much talked about subject but this was much worse then I expected. So I wanted to touch base with the group and share my experience and get some advise.

First we have a Rockwood Roo 19’ 2013
We spend most of Oct in the woods, Last week we spent 10 days in the woods in MI temps swinging from 28deg -60deg depending on the day. We had very bad condensation to the point where I see water damage on the corners where you can see where the water pooled up on the ledge going in to the bunk. We had to wipe down almost ever day if you didn’t want your pillows and sleeping bag to get wet. I did a lot of reading on this before we bought the new camper this year, and did everything everyone suggested (I wanted to do it right the first time) we have had PUP, and wall tents over the years and this was the worst I have see the water.

Most the time we have 2-3 people sleeping in the trailer. And the temp inside was 60-68degs

Ok here is my situations and what I though was the right thing to do.
1. We have popup Gizmo’s
2. We put reflectix in all the windows and under the mattress.
3. We had fans running to push the air in to the bunks
4. We ran the Generator all night so we could use the electric heater on low.
5. Used the main furnace when temps dropped below 60degs
6. Used the heated mattress pads.
7. Cracked the vent in the bathroom. After noticing how bad things where getting. Day 3ish
Things I didn’t do
1. We did no cooking in the trailer.
2. No showers at night and when we did use it window and vent fans where on high.

Now from everything I have read this all this should give us our best chance to reduce condensation. And this was worse then anything I have seen in the past. It was everyplace on the bunk ends except the windows where we have the reflectix.

It did rain a lot last week, but for comparison my dad had a PUP that we put tarps over the whole trailer and they ran a M-Buddy heater 24/7 with a few windows cracked and they had very little condensation and it was at the end of the trip and they boiled water for hot cocoa everyday inside.


Any suggestions would be great I’m really worried about my bunk end rotting and molding with that I seen.
I think I might be better off running a small dehumidifier vs the E- heater does anyone know how many watts they pull I got a Honda 2000, but I don’t want to run it on high all night if I have other options.

Thanks Zug

  • Does anyone know how many watts a dehumidifier will draw I tried looking online but it’s not on any description I have seen, if it draws less then 800-1,000 watts I could possibly make it work with my 2,000w Honda.

    I’m thinking maybe I didn’t have enough air flow at night I had the vent cracked and a fan running but with out another source of air I’m guessing it could not escape (kinda like blowing in a bottle) I hate to run the vent fan and crack a window, I would lose so much heat so quickly the furnace would never shut off. Maybe this is why it was so much worse then the PUP was because it much more air tight.

    Thanks everyone,

    The dehumidifier I am using is about the size of a twenty gallon ice box and sits in our shower . We can dry out clothing over night and, as said previously, have eliminated the problem. Also great for drowning out outside noise. I do not sell these for a living. It just solved the problem for us. We bought the unit at Home Depot and it is really more for a small house.


    Any chance of getting the size of the unit in pints or quarts, or the brand and model? I take the house dehumidifier when going to the beach off season, but it's big and heavy.

  • I keep the curtains open in the upper bunk, and run the fan only on the roof top air as well as the furnace to heat. This works pretty good on our class C.

  • X2 on dehimidifier. 3 poeple produce a lot of moisture in your breath, never mind cooking & washing. When we wintered over in Canada, our dehumidifier would take out 4-6 qts of water everyday with just 2 of us.
    Whenever you can fan & vent that humidity. Use the furnace more, its fan does more air movement.

    I have shared this cure before and got mixed reviews. If you have AC power run an electric dehumidifier. We do and have eliminated the issue completely. We were just out last weekend and dumped an amazing amount of water collected from our HTT interior. We kept the inside humidity at about 40. Dry everywhere.



    I like the idea but I'm only running a Honda 2000 I'll need to look and see if I can find a good energy efficient dehumidifier not sure how many watts they draw and I would hate to run the gen at warp speed for a week.
