Welcome to FRF!
We don't have hybrid but I do remember when we had a pop-up of getting lots of condensation on the inside canvas over the bed if we didn't have enough fresh air coming into the trailer. Don't know if the moisture under the mattress is condensation also...could be if its only damp where the mattress touch the canvas.

You may what to try adding a piece of insulated material between the mattress and the base where the mattress rest on. The material that I am talking about is the silver sun block that people place in there windshield of there cars. If the base is cold and the mattress is warm condensate will develop on the warm surface which would be the mattress. Cool or cold air may be passing by under the base of your mattress support.

as a suggestion, you may want to ask questions specific about hybrids on the Expandable section here.

this is a common issue with FR hybrids. other hybrid, like Starcraft, have vinyl on the bottom of their mattresses. these seem to be less vulnerable to condensation, as the FR hybrids are. but it may be that the moisture just stays inside the foam.
the FR hybrids have a fabric bottom and the heat of the humans radiates to the coolness of the bunk door. this causes moisture.
some have tried Reflectix underneath. we had some success but it didn't eliminate it.
we are trying an old wool blanket with the Reflectix. we hope this will allow some air in between and some heat reflection.
others have tried a product called Hypervent. it's used in marine applications and is expensive. they also had limited success.

Great question (as this was the reason I found this forum) and some good suggestions.
I hope others might jump in and add their $.02
We have an '07 Roo with the same issue, and only while cool/cold weather camping.
Just came back from Algonquin last week and our mattress was soaked... not impressed to say the least.
I hope FR is looking into this, as we really enjoy this product, and are hoping to upgrade in the next year or two.

Hmm! I have a Surveyor hybrid made by Forrest River and it does not have fabric bottoms on the mattress! Place some insulating material under the mattress and the problem will go away. Put Popup Gizmos on the tent ends and the problem will go away.

Both of our Coleman/Fleetwood pop ups also built up condensation on the roof/ceiling canvas over the beds. It had something to do with the inside temp with the AC on, being colder than the outside temp in the heat, but really only in the mornings. The Coleman's also have vinyl undersides on their mattresses, so no problems under there. Randy

i doubt that FR will do something. this problem occurs with other brands, also.

the last nite of our trip to YNP, we tried a solar blanket and wool blanket combo under our mattress. the results were encouraging. we had hardly any dampness. we will try it on our next trip which will be next month.

the brands that have the vinyl-bottomed mattress may not be damp underneath but the inside foam may be.
