Kids vent way too hot

We had a couple cool nights in our 390qsmb and noticed that when the heat is on, the heat vent in the bunkhouse is like one of those propane torpedo heaters and it blows straight at the mattress. Any ideas on how to fix this? We have thought about putting a deflector on it to at least direct it away from the bed and kids legs, but that would likely interfere with the slide. Any ideas are welcome. Thanks!

Ours is the same way. The furnace is right behind the wall and it's the path of least resistance. We did a lot of camping this early spring when it was still getting cold. I popped off the grill and covered 80% of it with heavy duty aluminum foil. It worked great.

I had a feeling you would have a solution. I'll give this a try soon. Thanks!

Also check yo make sure the other paths aren't blocked. We had a large volume of air coming out the bathroom and kitchen vents but nothing g really coming out the bedroom vent. It turned out some tubing/pipes or whatever was causing a blockage. So certain the air had an obstruction further down, it just came out heavier in other places (think similar to closing a vent in your house and how that affects elsewhere )

Hot heater vent

I had a similar problem with my trailer except it was the bathroom vent that was hot. The technician at my dealership talked to the furnace manufacture and was told to "NEVER" partially block a vent. There is a sensor that will shut the unit off if there is too much back pressure. That is why our rv's don't come with variable vents. They told the technician to add a couple feet of flex duct and that solved the problem.

Sure. A CYA comment I would expect from a manufacturer trying to reduce their liability when someone does something stupid. Basic understanding of fluid dynamics, pressure gradients and volumetric air flow give me more confidence than a broad stroke warning. My current 42 ft, 400+ sq ft, trailer has the exact same furnace as my old 30 ft, 275 sq ft camper with half as many furnace ducts. I'm pretty sure blocking part of 1 vent isn't going to burn anything down. I'm far more concerned with the extremely hot blast going right into the side of the pull out sofa.

We had to install damping registers to our 360 for the same problem.

This is the living room vent. I'm guessing it's not supposed to be like this...

Wow. I'm surprised you're complaining about heat in the kids bedroom and not cold in the living room!!

I'm sure that will be an issue if we have a really cold night. We have only taken it on one trip so far. Most nights were warm, but we had a couple cool nights. Just enough to turn on the furnace for bed time.

Luckily it wasn't constantly on. I am worried my son will stick his leg in front of it while he's sleeping and get burned.
