Tents is tents. Hybrid's and popups lack the tent roofing of must $500 camping tents. The better free standing tents have double roofs. The top layer is totally waterproof, the inner layer is breathable. These don't get condensation on the inside layer where it can get you wet.

Ventilation and dry air movement help our camper. Fan blowing INto the bunk area helps keep the tentage condensation free. The ventilation is paramount.

LEMII, don't take this wrong but there has been tons of posts on this subject in the psst months, in fact there may be hundreds of posts about condensation in hybrids.
did you not read them

Nope, I should have done a search first, but I didn't think about it.


or weren't aware this can be an issue with hybrids or popups? i realize that you may not have read them because you didn't realize it may be an issue.

Intuitively I thought this could be an issue based on my tenting experiences, but I didn't realize just how much condensation would develop on colder days.

this is the #1 question asked about hybrids and has to be constantly answered if a new member doesn't do a search or doesn't know to do a search.
there should be a Condensation Sticky at the top of the forum.
I strongly agree. Any issue that is common to all hybrids should be a sticky.

as was said, a little ventilation/air movement and PUGs will help a lot. they also reflect heat in the summer from direct sunlight and keep the bunk ends cooler. you just flip the silver side up.

an alternative to PUGs are solar/all-weather/sportsmen blankets. they are made of the same material and are available at REI, Cabela's, Campmor and maybe Bass Pro Shop. also available at internet stores, like High Mtn.s Store. they are a standard 5x7 size and may fit your canvas ends. but PUGs are custom-fitted for your hybrid and come with great customer service from Bob, the owner.

a side benefit to PUGs/solar blankets is that they keep the canvas clean from stains/debris and help darken the bunk ends for naps or late risers.


Thanks for the feedback!

LEMII, i hope i didn't offend you, i didn't intend to.

i hope this info helps you solve your problem. just a couple of notes.

condensation will occur in a regular TT also, if the same factors occur. there a thread with a TT owner who paid extra for insulated windows and had 5 people in a sealed up trailer. he had tons of condensation. so it isn't exclusive to canvas-type RV's.
second, you may have moisture under your bunk end mattresses, as dadmomh talked about. no one has found a complete cure for this yet.
we've been experimenting with Reflectix and a wool blanket. still trying to find the right cure.

Last time this subject came around I questioned just how you can warm up the ROO when it's 30 degrees outside when you open a window or bunkend even just a little. We did that, in addition to the AC/furnace fan running and the bunkend fans running, and it helped. BUT.....if we had someone sleeping in the rear bunk they would have frozen. And DH goes crazy if he feels a cold draft (NOT the beer, the air!), so do you slightly open the window by the kitchen area? The one over the sofa? Or the bunkend? We're getting in one more trip this weekend and temps are supposed to drop below freezing, so know we'll have condensation to deal with. What is the best area to leave slightly open?

Condensation comes from your warm body's exhausts into the cooler atmosphere.

Leaving a 3" gap in the zipper of your bunk ends window (not the sides, just the very end) on each bunk aids greatly in balancing that. Your zipper ends must meet at the very top of that window to do this obviously.

No one can argue with any reasonable sense that gizmos or home versions of them assist greatly.

Moving the ambiant temperature air is elementary. Don't have the 12V fans for the bunkends or don't care to use them, run a small fan on the dinette table or other air on oscilate even if it is 20 below zero. It's the movement of the air altering the ambient.

I had popup campers with my sweety before the Roo and we never once had a condensation problem, neither have any friends or relatives, and all of us rely on venting the zipper top and/or gizmos (or their version of) A few use fan movement as well (like Mom with her hot flashes, love you Mama!) If you buy a used camper, you can aid a tiny weensy bit if the poles are not already a powder type finish, by adding that.

No offense taken. I appreciate the suggestions.

Can't get input from new posters and a possible new idea if the questions don't get asked. Keep them comming LEMll.
