No blown air to bathroom or main bedroom

[crash999]

We have a Crusader Lite 30BH and there is no blown air coming out of the vents of the bathroom or main bedroom.
Any suggestions of how to remedy this?
Thanks

Is this the a/c vents in the ceiling? or floor vents for heat?

Its the floor vents. Its significant that the flow is very low at the far end of the ducting maybe I should try and limit the flow on the adjacent vents to the furnace? My guess this is just how it is.

This is typical RV construction quality. In most 5th wheels the bedroom and bathroom is fed off of individual round air ducts.

You will need to access the junction box where all of your duct work splits off from the back of the heater. Make sure they are all connected and have no kinks in them. You might also need to get some aluminum duct tape and tape up all of the connection points.


Also check to make sure the distribution box is connected properly to the back of the heater. Mine was just taped on one side and when the heater came on it would open up and most of the heat went into the basement.

Good luck

Thanks for that, as usual it's the poor quality of construction that causes problems.
We have a crusader Lite 30BH and the Bunk bedroom is like a fridge the insulation is so poor. I'm trying to figure out how to remedy this maybe by attaching polystyrene sheets to the outside.
We are static for 6 months of the year, then we put it into storage going home to the UK for the summer.
