Bathroom heater vent not blowing

Is the bathroom area visible from below in the 5er basement? If so you should be able to trace the paper thin dryer vent "slinky" that runs from the furnace to the floor vent. Following it from source to opening should show you if theres any reason its lacking flow.

X2 you might be expecting more than it can give.

If the vent is hot, it is getting flow, otherwise it would not get warm. Lay a piece of toilet paper across the vent to see if it moves.

Thanks for the advise. Will try all of the suggestions. This is our first 5th Wheel. Have had motorhomes. This is our first total inspection after we bought and brought it home.

New problem OR existing problem?

Vent is HOT....where?
AT the register or at the furnace discharge plenum connection?

If Duct is connected at furnace discharge plenum and register is hot then you have a collapsed/obstructed duct.
Cheap inspection camera own the register and/or in thru duct at furnace

I would suspect it has come loose or is kinked in the basement where it comes off of the distribution box. The bathroom is usually on a individual duct and if yours was built like mine was it probably needs some attention with some duct tape to close up all of the leaks.

Good luck
