I Know someone can help me on this. We have a 2013 5th wheel, a coachman Brookstone - when I turn on the heater in the coach only the duct in the bathroom blows hot air through it. Theres other vents in the living room but only a tiny trickle of air comes through it if any at all.

Let me know what you think, I appreciate any input

Thanks

Questions.
Is the vent with the most air flow the closest one to the furnace?
Is this a new to you 5er ? Or a problem you just noticed on a unit you've had for a while?
If there is a chance the problem has been there since the RV was new then.
You may need to look into borrowing a flexible camera to check out the duct work for restrictions.

My guess is a blockage in the duct work. Not sure if a drain snake could be used to check it.

Have you tried blocking off the bathroom vent and seeing if there's an increased air flow in the other vents?

Rarely do I see blocked duct, but more commonly a disconnected duct from the register. And DON'T snake it, they will tear.

And we are assuming you mean the propane furnace, and not heat strips or heat pumps, right? Different duct work.

X2, the furnace may use different ductwork to feed the different outlets and with a disconnected duct, you may be blowing hot air into the basement or right back into the furnace intake.

You may need to pull the register and vacuum the area below it.. Also one of those long small vacuum tube attachments might be needed (Doubtful but who knows) to get into the duct work

Also if you can inspect the furnace to see if any ducts came OFF the housing (This will likely require you access the inside side).

Air flow is not as strong as your sticks and bricks furnace, but the area needing heat is not as large either.

Thanks for your advice everyone. Once I know what the problem is I will post it

I had one that a mouse had carried paper and what not, and built a nest blocking the vent hose off almost completely

Bought a new 2014 Rockwood 8289WS RV 12/30/13. The vent in the Bathroom and on the step landing just outside the Bathroom had so much air coming out that it would run you out of there and almost nothing coming out of the vents in the living area. Was told by two different dealers "thats just the way they are, they are all like that and to use box fans. The thermostat is at the stair landing also, it would turn off the furnace long before the living area got warm. I'm a DIY guy so I dug into it and replaced the plastic floor vents with metal vents that had dampers in them and closed off the BR and landing vent, not much help. I got into the furnace and with a couple pieces of sheet metal I blocked off 1/2 of the 4" openings to the BR & landing taps from inside the furnace. The vents going to the living area were scrunched up pretty good at the furnace and at there taps. I bought a couple 4" aluminum 90º ells from Home depot installing them at the furnace taps to the living area. I stretched out and cut off excess flex ducts connecting them to the installed ells. Now there is way more airflow to the living area and way less in the BR and landing vents. Had two pieces of the flex duct about 4' long that got cut out and trashed. Picture is of the aluminum 4" 90º ells attached to the furnace tap and flex duct. The RV is pretty comfy on the cool 40º mornings.
