31QBS - Furnace Vents

[JAMHud3]

Does anyone else have any issues with furnace vents not working. The 31QBS has 5 furnace vents and 3 of the vents does not blow hot air out. Checked the furnace and noticed that the three vents that do not blow have smaller ducts (hoses). The two vents (bathroom and left Kitchen table vent) that blow pretty good are larger ducts. Is there baffles that need to be opened to get hot air to blow to the three non-working vents or do I have another issue.

common problem with them. we all have that same issue with our units.
small one to front bedroom is run farther and snaked through the botttom of bathroom sink. No room to run a larger vent into that room. Yes it's cooler, next to none. Bathroom is HOT HOT hot. There is no heat vent into bunk house, that vent under seat is for electrical heat to breath. Some owners have found regulating vents for them and installed them. We just leave the bathroom door cracked open to move the air around. We are use to it and I does not bother us. you don't stay in bathroom long though.
one vent goes into floor to heat under belly.
apparently trhe furnace has to have so many big one and not be restricted for proper operations.

We have the same issue, its just poor duct design. We leave the bathroom door open to get the heat out from there. Dont close the door to the bunkhouse if anyone is sleeping there. There is not enough gap under the dooor to get heat back there. If the bunkhouse gets to cold you may want to try to get a small electric heater to put in there.
