Front Window Condensation Issue-3811ms

We have a 3811ms and have had an issue with water pooling up from condensation at the inside bottom of that front cap picture window. Has anyone one else had or is having this issue? What can we do to reduce or eliminate this issue? Thanks in advance for your replies.

PS- Warning...took our 5'er in for a Electric Power Cord Reel replacement and told the tech to also look at the hot water heater. The caulk was pulled away from the wall almost all the way around one side of our water heater. Come to find out it came from the factory WITHOUT any of the four screws/bolts it was supposed to have that hold it in. It now has those four screws/bolts and should not work itself loose. It traveled over 1400 miles with only the water lines, gas piping, and caulk holding it in the wall. Check your hot water heaters. God was watching over ours and kept it in the wall.

We have never had a unit with the big window in front, but did have condensation issues when we were in GA and FL and had to use a small dehumidifier to solve the problem. Never had the issue wintering in NM and AZ.

when winter camping, or anytime using the furnance, we have always kept a roof exhaust fan running. we had 3 children and the DW and I, just our breathing will contribute to condensation. we noticed an improvement within a day.

Your propane furnace generates quite a bit of moisture that will need to be ventilated.

I would certainly hope not. If you are getting moisture that would indicate the firebox has failed and you are getting CO poisoning. The combustion portion of the heater vents outside.

The windows on most any RV will have condensation in the cold ... it's just one of the joys of RVing in winter months. Single pane glass more so than double pane. Take the above advice of using the vent and/or a dehumidifier ... it will be reduced to a tolerable level.

Single pane windows will easily have condensation with the furnace running in high humidity areas. We rarely close one window in the bonus room and leave that door open a crack.

Remember from your physics classes...Heat Flows

Cold windows draw the heat energy toward them. That energy is in the air. If the air is full of moisture it will condense on the windows as the heat is drawn out. You will notice the air that has had the heat energy pulled out of it falling as cold air at the bottom of the windows.

FWIW

Try a small oscillating fan pointed at the window, Moving the air maybe won't let it settle on the window. It won't take much.
