We have a 2014 Passport Ultra Lite Elite . At the head of the bed, located against front wall is a seam strip 10" above bed base. Our temps are in 30's-40's and the section below seam is wet with condensation . The area above is dry. The outside is seamless fiberglass. Could it be due to omission of insulation in that area ? ....or ?

You have a water leak. Pull off the inside paneling and find out. It won't get better by itself.

Probably condensation because of poor insulation and low air movement inside. Keep the mattress pulled away and get more ventilation. It seems counter productive when heating but must be done.

its where hot air is hitting cold air causing condisation on the wall use a fan pointed at the wall and pull the mattress a few inches from the wall

If it's under the mattress, it's condensation from body aspiration of moisture (sweat). If it's above the mattress, you have a seal failure issue and water intrusion. Have you maintained your seals in accordance with the builders guidelines?

It won't get better, only worse and needs to be addressed pronto or your RV will become a pile of rotten moldy garbage.

If you are plugged in, put a fan blowing at the place where condensation is happening. Gas furnaces pump out moisture, and it will seek out the coolest spots to settle on.

Get yourself a laser thermometer and point it around the rig near where this occurs. The thermometer will sense the possibility that insulation might have slipped down inside the wall causing this problem.

It's not unheard of for them to miss a fiberglass batting or two during construction, and the front of that trailer looks like it contains batt insulation. I think you are probably correct that there's missing insulation there. That's also about where the transition from sloped to vertical happens, which often has lots of framing and stuff versus insulation.

If you ever have reason to tear into the dead space between the front nose exterior and inner wall on a travel trailer or 5er youll most likely find all the batt insulation installed at the factory laying in the bottom of the cavity. You may not find any insulation at all.

In areas hidden to the buyer these low grade schmucks who call themselves RV manufacturers do all sorts of shoddy stuff. Look above a coroplast underlining. Then again don't...out of sight, out of mind.

In addition to the many good ideas above, if you roof vent covers that are installed over your roof vents, open them. If you do not have roof vent covers, get them...they are not that difficult to install. In this rainy NW climate I keep my roof vents open 24/7/365, even when we are underway. Allows moisture to exit and we experience no inside condensation since I started this practice 11-12 years ago.

Unless you have a leak as several have mentioned, the above should greatly reduce or eliminate condensation as the culprit.

I run a dehumidifier in my Passport any time I camp in colder weather. It gets lines of condensation where all of the aluminum frame bars are.
