High Winds: Cold Air Flowing into TT

While camping at Zion the wind was brisk. We woke up one night and the area around the head of the bad was "freezing." Cold air was coming up from the head area and on both sides on the bed. In the MRB there is a "blank storage area" across the front of the TT with a storage area on each side; the photo is looking from one storage area to the other side of the TT. Hard to see, but in this area the front of the area is not sealed. In the second photo, it shows the bottom of the drawer (one on each side of the bed). This drawer is visible when you open up the outside storage door. While the outside door has a seal, I can't help wonder how air tight it might be.

Has anyone ever tried to seal off these areas? I am going to try it as it seems to be the only way to stop wind from flowing into the TT.

One other interesting note. We have 3 heater ducts. During this high wind, cold air flowed through only one of the ducts and into the TT. I wondered if it was coming through the heater exhaust.

On the way back from a 12 day trip to Zion and Bryce and loved it! TT performed beautifully.

On my 23MBH I sealed and insulated the underside of the bed frame. Before I did that the draft coming through would freeze my face at night.

The cold air through the duct was probably coming from the duct that is in the underbelly. There isn’t a pathway from the furnace exhaust to the ducts.

My 24RBS had similar openings under and around the bed area....., refer to my Post #26 in my Mod thread for my fix:

I haven't gotten to sealing mine yet, 28 BHBE(waiting for spring), but the area between the bed board and "end tables" is a piece of vanier that doesn't even fit. I plan on stapeling some insulation on this then a sheet across the top of the entire pass through. I use the aluminum bubble wrap sheets at Home Depot.

This is the area I am referring to. Look at the thin venier....

Yep, I have that same thin veneer in my storage areas. Rustic Eagle had a great idea above which I am going to try when I get home.

Page 15 of my thread shows similar where I separated the pads through from the inside and rebuilt everything to make it stronger.

We put a blanket under the mattress that covers the plywood and extends past a short distance and have had no issues even down to the teens. May want to also check how tight your storage doors close, you may need to "adjust" the tension on the lock.

I just added a baseboard type heater in my “basement” on very low heat because that area is not outside but not heated either.

I blamed the front wall as the culprit of the cold air.

I just discovered the same thing as Kidd280 while working on a solution. The front plastic piece (there must be a name for it) the shield the lower part of the trailer is placed so there is a 3/4 gap between the front and the floor of the trailer. Prior to putting down any insulation or barrier I need to fill in this gap. I am not sure whether to just stuff some insulation in there, use expandable foam, or actually cut and place some type of barrier and then seal it with caulking.
