Condensation on 147x tent ends

Hey guys Just got a 147x,
AND NOTICED after our first trip there was condensation under the mattress, enough to make thr mattress wet.
How have you guys solved this?
Thinking about trying foil backed insulation.
Any help would be appreciated.

On a hybrid or popup it is IMPERATIVE that you keep the tent ends cracked open and run the bathroom fan. You and family breathe out a lot of moisture and it condenses on anything cold. Start with that. If you still have problems, then something under the mattress may help. You can run the furnace to keep temperatures comfortable, or if you have electric hookup, get a small 1500 watt space heater.

A lot of hybrid owners who camp in extremely hot or cold conditions buy Popup Gizmos (PUGs) to help with condensation on the tent ends when cold and help the air conditioning keep up when hot.

Many also put Refletix in their tent end windows.

This is very common on PUPs with the bed bottoms exposed to cold air. The moisture from your body penetrates the bed and condenses on the cold bed platform. When we had our pup, we used this self inflating ( hiking) air mattresses which greatly reduced the condensation. You can also add a thin sheet of construction foam sheeting under the mattress. When we camped in cold weather, we always took the mattress out and aired it for a day or two ( upside down) when we returned home.

I used foil backed insulation with limited success.
I have been using a wool blanket underneath, with better success.
It's good to find a way for some air to move under the mattress.
The blanket is porous enough for that to happen some.

Went through this when we had a hybrid. I tried all the usual advice of leaving tent ends cracked open, running the bath fan, pop-up gizmos, vinyl mattress cover etc.
The only thing that worked was using the 1" foam insulation that is sold in sheets (4'x8') at places like Lowes, and placing it under the mattress.

Has anyone tried the interlocking rubber mats? I was thinking about adding those to get a little more comfort as well as hoping it would keep the underside of the dry.

I think you will find the rigid Styrofoam lighter, less expensive, and easier to leave in place when folding up than the rubber floor tiles.

We have two Thermarest camp pads that we slide under the matress. This makes it far more comfortable and also insulates us better than just the mattress.

I'm definitely going to give this a try.

Thanks
